NEW YORK -- The Mets have likely lost top starter Jacob deGrom for the season after the right-hander experienced pain in his elbow Friday.General manager Sandy Alderson said the pain is ulnar nerve-related and likely will require surgery. The Mets believe deGrom is experiencing something common for pitchers who have had Tommy John surgery: a buildup of scar tissue that presses on the nerve.Its unlikely hell pitch again this season, Alderson said.DeGrom had the Tommy John surgery when he was a minor leaguer in 2010, although he said a recent MRI showed no structural damage.Ive been through Tommy John before, and I definitely dont want to go through that again, so I think this is good news compared to what it couldve been, he said.Alderson said its not unusual that an issue with scar tissue could arise even this far removed from Tommy John surgery.DeGrom, 7-8 with a 3.04 ERA, had thrown a pain-free bullpen session before batting practice Friday, leading to him being cleared to start Sunday against the Minnesota Twins. He ran sprints and then took his spot in the outfield shagging flies.He felt pain in the elbow while throwing a ball back to the infield and knew it was a problem.I just tried to lob it into the bucket, and I guess throwing that bullpen messed with that nerve, and after I threw it I said, OK, Ive got to go say something, deGrom said. One throw, that I felt it on, and it was definitely disappointing.Mets manager Terry Collins will use members of his 12-man bullpen to get through Sundays game. Gabriel Ynoa (1-0, 15.19 ERA) will start vs. the Twins.?New York had to use eight pitchers to get through its 3-2, 12-inning win against the Twins on Saturday night.?Earlier in the day, DeGrom said he has been experiencing numbness in his ring and pinkie fingers for weeks, and that there was actual pain when he was last on the mound Sept. 1, when he gave up three runs in five innings and suffered a third loss in as many starts. Over the two previous starts, he gave up an uncharacteristic 13 runs in 9.2 innings, but he felt the numbness returning even before that.I havent felt it all year. It mightve been five or six starts ago, he said. I had a couple of good ones with it -- when the fingers were going numb -- and I was just like alright, whatever. Then I had a couple of bad ones and I dont think thats the reason I had bad starts. I just think I just wasnt able to throw the ball where I wanted to because I wasnt feeling really any different than when I had the good ones.But now its kind of turned into a pain, and we want to get that taken care of.DeGrom said the surgery to liberate the ulnar nerve could either involve removing scar tissue or relocating the nerve itself. There is a typical three-month recovery period.Alderson added that the procedure is not a significant surgical procedure, at least with respect to risk going forward, but its something that will have to take place at some point.?Both Alderson and deGrom left open the possibility of trying to get the ace back on the mound before the end of the season, but it remains a longshot because, as Alderson noted, the fact that this thing flares up at unpredictable times and unpredictable circumstances.The Mets have been getting rotation help from call-ups Robert Gsellman and Seth Lugo. The team has stabilized a rotation that lost Matt Harvey to season-ending surgery to treat thoracic outlet syndrome; the Mets have been without Steven Matz for a month and deGrom for two weeks.Since deGrom was sidelined, the Mets have won nine of 13.The news still soured things at Citi Field, where the Mets hosted the Twins on Saturday on Jacob deGrom Hair Hat night. They entered the night two games ahead of the Cardinals for the second National League wild-card spot.[This is] nothing any more damaging than the other ones that weve had and didnt expect, Collins said. I actually watched Jakes bullpen yesterday and it was outstanding. And 15 minutes after batting practice was over, he walked in and said, I cant pitch. He explained what happened and you shake your head and the next thought is, Who is going to pitch? So youve got to move on and find somebody we think can get somebody out. Well go from there.With deGrom lost, Bartolo Colon (30) and Noah Syndergaard (28) will be the only Mets pitchers to make 25-plus starts this season. Last year, Colon (31), deGrom (30), Harvey (29) and Jon Niese (29) all did so.DeGrom threw 191 innings in the regular season last year -- 216 counting the playoffs. His previous high for innings in pro baseball was 178.2 in 2014, when he was called up in May from the minors for the first time.Information from ESPN Stats & Information was used in this report.

EDEN PRAIRIE, Minn. -- Adrian Peterson was back on the practice field on Wednesday for the first time in nearly three months, and the Minnesota Vikings hope their star running back can give them the jolt they need to chase down a playoff berth.Petersons rehab of a torn meniscus in his right knee is nearly complete, allowing him to rejoin his teammates at practice as he ramps up for a highly anticipated return. Wearing a black brace on his right knee, Peterson took handoffs from Sam Bradford, ran routes and went through some agility drills during the portion of practice that was open to media.Peterson was not available for comment on Wednesday, but did tell a local website earlier in the week that he is still targeting the Dec. 24 game in Green Bay for his first game since the injury against those same Packers in Week 2.Coach Mike Zimmer did not rule out Peterson playing against the Indianapolis Colts (6-7) on Sunday, but that appears optimistic at this point. Peterson said last week that he likely would not play in a game this year if the Vikings (7-6) were eliminated from the playoff hunt, but after beating Jacksonville last weekend they remain very much in the mix in the NFC.Hes been a leader on this team. Hes one of the best players in this league and he has been for quite some time, Bradford said. I think just having him back out at practice in the huddle, I think its a definite lift to our guys.The Vikings are operating under the assumption that they have to win their final three games to get into the playoffs, and Petersons return certainly would increase those odds.The Vikings offense has struggled mightily to score points and make big plays this season, with an injury-riddled offensive line the primary culprit. Getting a player of Petersons dynamic ability back into the lineup should help a rushing offense ranked 31st in the league, especially one that sttruggles in short-yardage situations.dddddddddddd The Vikings were stuffed on four downs near the goal line on Sunday against Jacksonville, and Petersons nose for the end zone, vision and power could make a dramatic difference in that area, among others.Any chance you get to add Adrian Peterson back to your lineup, its a positive, Bradford said. I think well definitely take him back in the lineup regardless of if theres any challenges or not.Zimmer was pretty tight-lipped about Petersons presence on Wednesday, not looking to make a very big issue out of it when the timeline for his return in a game remains in question.Whenever he does return, Peterson will be coming back to a different offense than the one he left in Week 2. Offensive coordinator Norv Turner resigned in November and the Vikings elevated tight ends coach Pat Shurmur to that position.With running backs Matt Asiata and Jerick McKinnon struggling to make big plays and Bradford under siege behind a leaky line, the Vikings retooled their offensive attack to feature more quick passes. Thats a big change from the Peterson-centric offense that the running back has been accustomed to for most of his career.Its like any player that comes back, Zimmer said. You try to figure out what they do well, how they fit into the system and things you need to change.Bradford was not concerned about accommodating Peterson back into the fold.Obviously its a little bit different than the first couple weeks of the season, but Adrians a great player and Im sure hell be able to adjust, Bradford said. We will find some things that hes comfortable with, some runs that he likes that theyve had success with in the past.---For more NFL coverage: http://www.pro32.ap.org and http://www.twitter.com/AP-NFL ' ' '
