GAINESVILLE, Fla. -- No. 23 Florida likely will be without quarterback Luke Del Rio against Southeastern Conference rival and 15th-ranked Tennessee next week.Del Rio injured his left knee in a 32-0 victory against North Texas on Saturday night, a huge setback for the Gators and their championship hopes.It doesnt look great, so well do whatever, said coach Jim McElwain, adding that former Purdue starter Austin Appleby would be the next guy up. Somebody else will play and well get some guys ready and move forward and get ready to go play next week.The injury overshadowed a dominant performance by Floridas defense, which allowed a school-record 53 yards on 50 plays. The previous mark was 59 yards allowed against Western Carolina in 2006.Defensive lineman Joshua Wheeler hit Del Rio low at the end of incomplete pass late in the third quarter, drawing a personal-foul penalty. Trainers and coach Jim McElwain rushed to the field as Del Rio ripped off his helmet. Del Rio eventually got up and walked to the locker room without any assistance.But that was hardly the end of it for Florida (3-0). McElwain, who clearly believed Wheelers hit was dirty, started yelling at the North Texas (1-2) sideline and had to be restrained by officials and then his players.When you see something like that, its my responsibility when their parents arent here to be their parents, McElwain said. I care about these kids. Theyre mine. I see something like that, it aint right.Both teams responded to McElwains tirade by stepping onto the field and moving toward the hash marks.He was trying to make a play and didnt mean to do it, North Texas coach Seth Littrell said. We are not trying to take cheap shots here.On the next play, Florida guard Martez Ivey was ejected for grabbing linebacker Fred Scott by the facemask during a run. Ivey will not be suspended for the first half of next weeks game against the Volunteers.It got a little gritty after that went down, Florida left tackle David Sharpe said.Del Rio completed 14 of 25 passes for 186 yards, with an interception.THE TAKEAWAYNorth Texas: Littrell, a former offensive assistant at Arizona, Indiana and North Carolina, is trying to change the culture at North Texas. Playing the Gators tough early -- the score was 19-0 through three quarters -- was a good start and something to build on in Littrells first season.Florida: The tune-up games are over. While handling UMass, Kentucky and North Texas, Floridas defense was dominant and its offense remains a work in progress -- especially without Del Rio. It remains to be seen how the Gators young and inexperienced offensive line will fare against the meat of the schedule.APPLEBYS TIMEAppleby started 11 games the last two years for the Boilermakers, leaving Purdue after 19 touchdowns and 19 interceptions. As a graduate transfer, he was eligible to play right away. You dont ever want to be somebodys caddie, Appleby said. You want the ball in your hands.McElwain said freshmen Kyle Trask and Feleipe Franks also may have to get ready to play.FOURTH-DOWN FAILURESFlorida could have scored more but got stopped on fourth-and-2 plays inside the 10-yard line. Mark Thompson was stuffed for no gain from the 5 in the first quarter, and Del Rio threw incomplete from the 8 in the second. The Gators are now 0 for 3 on fourth-down tries inside the 10 this season.NO CALLAWAYFlorida played without sophomore receiver Antonio Callaway, who missed the game because of bruised quadriceps. Callaway entered the game leading the Gators with 13 catches for 201 yards and two touchdowns. He is expected to play against Tennessee. The Gators got senior receiver Chris Thompson back, and he proved to be another deep threat. Thompson was suspended the first two games.POLL IMPLICATIONSFlorida should remain at or near No. 23 , making next weeks game at Tennessee the second in eight years in which both rivals were ranked. They also were both ranked in 2012. The Gators, who have won 11 in a row in the series, and Volunteers were both unranked the previous two meetings.UP NEXTNorth Texas: Opens Conference USA play at Rice (0-3). The Mean Green are 2-4 all-time against the Owls.Florida: Plays the Volunteers (3-0) for the 27th consecutive year. Florida is 20-6 during that stretch, including 11 straight wins that mark the longest streak since the programs first played in 1916.---AP college football website: www.collegefootball.ap.orgMarc Gasol Raptors Jersey .

SARASOTA, Fla. -- The Oakland Raiders will try to go 5-0 on the road for the first time since 1977 when they play the Tampa Bay Buccaneers on Sunday.The teams mettle could be tested with back-to-back games in Florida, however the Raiders remained in the state to practice at IMG Academy in nearby Bradenton instead of returning to the West Coast after a 33-16 win over the Jacksonville JaguarsCoach Jack Del Rio said the additional time in Florida has helped the team adjust to the conditions and stay focused on the task at hand.The biggest thing is not to have to fly back and forth, Del Rio said. As far as being here and acclimated I dont know that youre ever acclimated in the short time that were here. We understand what were up against. Weve traveled to Tennessee before and played in similar conditions in terms of heat.Quarterback Derek Carr credits the teams business-like attitude and camaraderie to their success on the road. Noting that when the team arrived in Sarasota many of the players were already starting to study film together in their hotel rooms.Doesnt matter where we at were family, Carr said. We could be here, in New York, doesnt matter. Our focus is on winning this football game. I could see it Monday and Tuesday night watching those guys and they are watching film in their rooms instead of being outside.The game will have special meaning to offensive lineman Donald Penn as he will play the Buccaneers for the first time since they released him in 2014. Penn spent eight seasons with Tampa Bay and made the Pro Bowl in 2010.Its going to be kind of weird, Penn said. Ive never walked intto Raymond James Stadium from the visitor side.dddddddddddd. Its going to be something new.Penn said is he doesnt want to make too much of his homecoming but said that hell play with a chip on his shoulder against the team that let him go.Its very huge, you know me, Im a straightforward guy, Penn said. (Being released) is definitely on my mind and something Im never going to forget. Good thing is Im happy where I am now. Carr said Penn has been a great teammate and a major asset to the team. He doesnt expect Penns return to Tampa to be a distraction as the game approaches.Donalds the best, hes like a big brother to me, Carr said. He wants to protect me more than anything. He gets mad if his guys finger touches my jersey. For him to come back Im sure hes excited. Its human nature. Its exciting, but once the game starts hes not thinking about it. Hes just trying to play to the best of his ability.EDWARDS JOINS TEAM: DE Mario Edwards Jr. joined the Raiders in Sarasota on Thursday. Edwards has been on injured reserve since the start of the season with a hip injury. He was eligible to begin practicing with the team last week but Del Rio said Wednesday that Edwards had not been cleared yet. The 2015 second-round pick is eligible to play in Week 9 against the Denver Broncos.JONES RETURNS TO PRACTICE: RB Taiwan Jones was a limited participant in practice Thursday after sitting out Wednesday with a knee injury.---AP NFL website: www.pro32.ap.org and http://twitter.com/AP-NFL ' ' '
