LAKE FOREST—For the second straight season, a triceps injury is going to end Charles “Peanut” Tillman’s season. Tillman, who re-injured his right triceps Sunday night against San Francisco, has been placed on season-ending injured reserve, the Bears announced on Monday.Tillman was injured in the third quarter of the Bears 28-20 win over the 49ers. Tillman appeared to be in considerable pain and seemed to know that his season might be over as he fought back tears on the sideline.The 33-year-old missed the final eight games of 2013 after tearing his triceps in Week 9 against the Lions. The Bears placed Tillman on IR-return last season, but they couldn’t do that this year because the designation can only be used once and the team used it on wide receiver Marquess Wilson.Tillman has been with the Bears since they selected him in the second round of the 2003 NFL Draft, but the cornerback’s time here could be coming to an end.The 12-year-veteran was playing this season on a one-year deal. It’s hard to imagine the Bears bringing back an aging corner who has dealt with two devastating injuries the last two years.The two-time Pro Bowler has started 156 games in his career, the third-most in Bears history.
