ORCHARD PARK, N.Y. (AP) - Buffalo Bills tight end Mike Caussin says he's been informed by the team that he'll be placed on season-ending injured reserve because his surgically repaired right knee has not yet fully healed.

Caussin revealed the news to The Associated Press before practice Monday, the final day in which the Bills had to determine whether to activate Caussin. The second-year player opened the season on the unable-to-perform/reserve list, which provided him a three-week window to return to the active roster after Week 8.

Caussin accepted the team's decision, saying his knee was not yet strong enough to handle the extra workload of practice over the past three weeks.

He had surgery in January after tearing two ligaments in a 40-14 win over Denver on Dec. 24.
