Bills running back Marshawn Lynch has been mentioned in trade rumors for a majority of the offseason, but an injury may be keeping a move from happening. Lynch hasn't played or practiced since Buffalo's first preseason game, when he suffered an ankle injury.

Bills coach Chan Gailey lectured some teenagers on Tuesday for heckling the team during practice. "If you dog one of us, you dog all of us," Gailey said. He said he'd instructed his players to skip that section of the stands for signing autographs on what was the final day of training camp in suburban Rochester. "They said some things during practice that were derogatory to a couple of our players," Gailey said later. "And if you say something derogatory to one of us, you're saying it to all of us."

Bills tight end Shawn Nelson has been suspended four games after he was suspended for violating the NFL's substance-abuse policy. Nelson, drafted in the fourth round last year out of Southern Mississippi, started 12 games as a rookie for the Bills.

Bills rookie running back C.J. Spiller was the team's main option in their preseason victory over the Colts on Thursday night. Spiller rushed 10 times for 54 yards, scoring on a brilliant 31-yard rush to open the game. He was targeted once through the air and grabbed a two-yard reception. He was featured after veterans Fred Jackson and Marshawn Lynch were injured earlier in the week. "I think you can see tonight why we drafted C.J.," coach Chan Gailey said of the player selected ninth overall out of Clemson. "Obviously, running the ball is what he does best. And he made an unbelievable run on that touchdown."

Former Bills defender Aaron Schobel says he's going to retire. Buffalo released Schobel on Aug. 4 after nine seasons and he initially indicated that he planned on continuing his career. "I really didn't have a lot of fun playing last year," Schobel said. "The passion wasn't there, so it was time. I took as much time as I felt like I needed to make the decision, and I think I made the right one."

Fred Jackson will be out four to six weeks with a broken bone in his left hand, sources tell The Buffalo News. The injury makes Jackson very questionable for the Bills' season opening game against the Miami Dolphins on Sept. 12. Four weeks from the injury would be Sept. 10, two days before the Miami game.

Fred Jackson suffered a hand injury in the first half and head coach Chan Gailey said he will miss the rest of the preseason. ?Fred hurt his hand and we hope to be able to get him back for the first game,? said Chan Gailey. ?We?re not sure.? Marshawn Lynch suffered an ankle injury that is Gailey did not know the immediate severity of.

The Bills plan to give rookie running back C.J. Spiller some reps with their starters. Spiller signed his contract late last week, meaning he missed 11 training camp practices. The rookie is in line to take reps with Buffalo's offensive starters, a source with knowledge of the situation told NFL Network insider Jason La Canfora on Sunday. Spiller, the No. 9 overall pick, received a five-year, $25 million contract with escalators that could make the deal worth up to $37 million.

The Buffalo Bills reached a five-year, $25 million contract with first-round pick C.J. Spiller that could escalate to $37.5 million, according to a source. The running back's deal includes $20.8 million in guarantees, according to a source.

Fred Jackson has been getting a majority of Buffalo's first-team touches at running back, according to Chris Brown of BuffaloBills.com. Marshawn Lynch is just doing the most with the reps he gets in the practice setting. "I'm sweating," said Lynch when asked if he was getting his fair share of carries. "I'm just getting in where I can." Asked if he is looking for a bigger role than he played last season when he had a career low 120 carries, Lynch left it in the hands of the coaching staff. "Actually man they're professionals at what they do too," Lynch said. "So I'm going to leave that to them and just come out and give what I've got every day. Whether they get me on the field, whether they have me playing the same role, whether they have me doing more, I'm cool with that."
