TEMPE, Ariz. (AP) — The Buffalo Bills have suffered another blow to their porous defense. Defensive end Mark Anderson will have surgery on his left knee and will be out indefinitely.
Anderson, who signed a four-year, $27 million contact prior to the season, suffered the injury — and had difficulty putting any weight on it — in the second half last Sunday during the 45-3 blowout at San Francisco.
"It looks like he needs surgery and he is going to be out. I don't know how long," Bills coach Chan Gailey said. "He will be back. It is not like he is going to miss the rest of the season. They just said indefinite and they will no more when they go in."
According to general manager Buddy Nix, Anderson will visit Dr. James Andrews to determine the severity of the injury.
That leaves 10-year veteran Chris Kelsay to take over the starting duties at right defensive end. Kelsay traditionally plays the left side. Kyle Moore will also see action and former All-Pro Mario Williams will remain at his left end spot.
The Bills are down to three defensive ends because veteran backup Spencer Johnson is expected to miss his second game with an ankle injury.
"(Anderson) has been a very good addition to our football team. You hate to lose people that have his kind of energy and have been playing the way that he has been playing," Gailey said. "It hurts your depth, it hurts your pass rush, and it hurts every little thing there. Next guy in line has to step up. We got three defensive ends right now and those guys are going to have to make it happen."
The Bills attempted to improve their defense by signing Anderson and Williams in March. The plan's been unsuccessful so far.
Williams, who has been hampered by a left wrist injury, has not played up to expectations, having managed just 1 1/2 sacks so far. The injury has bothered him since hurting it in the final week of the preseason, though he's not been placed on the team's injury report because he's not missed practice. That changed on Wednesday, when the Bills listed Williams on their report as having practiced fully with a wrist injury.
The move comes days after the NFL revealed it is investigating whether the Bills have violated a league rule, stating that teams are required to list players on their injury report even if they don't miss practice time. And the rule stresses that it's especially important to list "key players."
