MONTREAL -- There was awkward silence when Formula One drivers were asked on Thursday about the on-track antics of McLaren Mercedes Sergio (Checo) Perez. Aggressive driving by the 23-year-old Mexican has had veterans seething, especially Kimi Raikkonen, who suggested after the Monaco Grand Prix two weeks ago that some should "punch him in the face." The six drivers assembled for the traditional race week news conference at the Canadian Grand Prix didnt want to touch questions about Perez, until finally Caterhams Giedo van der Garge offered: "If nobody comments, I will." "I know Checo well. We were teammates in 2010. Hes a real fighter. Hes a guy who always wants to win," the Dutchman said. "How he raced in Monaco, sometimes he was doing well, sometimes he was going over. But its a tough call." Criticized for being too passive early in the season, Perez has gone on attack, leading to incidents with veterans like Fernando Alonso and even his own teammate Jenson Button. In Monaco, an attempt to overtake on a chicane led to a bump with Raikkonen. The damage caused the Finnish driver to drop from fifth place to 10th and lose valuable championship points. Perez was later forced to retire with brake trouble. Talk of Perez has even bumped the great tire debate from top billing this week. The F1 governing body FIA has called on its international tribunal to rule on complaints that the Mercedes AGM team broke rules on in-season testing when it recently did 1,000 kilometres of tests in its 2013 car on a new compound of Pirelli tires. The new tires are available for use by all teams in practice at the Canadian Grand Prix on Friday. They will get their first race workout June 30 at the British Grand Prix. Mercedes could have used reserve drivers for the tests, but elected to have both F1 regulars Rosberg and Lewis Hamilton on the track. "That was what the team decided," said Rosberg. "Also, for Pirelli, its better if were in the car because its more representative." He said reserve drivers wouldnt be able to maintain the same pace or "bring the Pirellis through the laps exactly as we do. So definitely for Pirelli its an advantage to have us in the car, for sure." The 11 teams will be on the track for practice Friday, with qualifying on Saturday and the race on Sunday. Rosberg, who won in Monaco, will be gunning for a fourth straight pole position this season. "Our car has been the quickest in qualifying for quite some time now,"he said. "We just have a very fast car. "Im confident Ill be quite far up the grid in qualifying here."

SAN DIEGO -- A month-long ordeal ended Monday, when?San Diego Chargers rookie first-round selection Joey Bosa?signed a four-year deal with the team.Scheduled to report on July 29, Bosa remained unsigned for 31 days before coming to an agreement.Bosa is at Chargers Park and will practice on Tuesday, but a team official told ESPNs Adam Schefter that the Ohio State product will not play in San Diegos final preseason game on Thursday against the San Francisco 49ers.Selected No. 3 overall by the Chargers in this years draft, Bosa remained unsigned for over a month, the longest a rookie has withheld his services under the leagues newest collective bargaining agreement established in 2011.We look forward to having Joey join us and getting him prepared as quickly as possible for the 2016 season, said general manager Tom Telesco in a statement.Things turned ugly last week in the contract disagreement, with the team pulling what it called its best offer when Bosa declined to accept it.The Chargers latest offer included paying 85 percent of the signing bonus by December, with the rest paid out in March. Bosas camp reportedly wanted all of the $17 million paid out by December, or the removal of offset language.According to Schefter and multiple reports, the Charrgers compromised on cash flow in Years 2, 3 and 4 of the agreement, giving Bosa the largest upfront signing bonus installment payment in team history for a veteran or rookie player.ddddddddddddBosa compromised on the offset language of the contract, according to Schefter and reports.Bosas salary is pegged at about $26 million over four years, with a $17 million signing bonus.?Traditionally, the Chargers have included offset language in contracts to protect the franchise from paying a players full salary in the event San Diego releases the player during the guaranteed portion of his deal. Think Ryan Leaf.Offset language allows the organization to pay the remaining portion of a players salary not covered by the new team that signs the released player. Without offset language a player can double dip, receiving a full salary from his previous team along with whatever money is negotiated with the new team.Bosas father, John, also was a holdout as an NFL rookie. John Bosa was a defensive lineman drafted No. 16 by the Dolphins in 1987 and held out 41 days before signing his rookie contract, according to ESPN Stats & Information. ' ' '
