Looks like Brett Keisel is done for season with triceps injury for Steelers — Ed Bouchette (@EdBouchette) November 30, 2014

The Steelers' 35-32 loss to the New Orleans Saints in Week 13 may have been the last time they will see defensive end Brett Keisel in a Steelers uniform.

Keisel suffered a reported triceps injury late in the loss to New Orleans, and the Post-Gazette reporter floated the notion that Keisel may be lost for the year. The 36-year-old Keisel was signed to a one-year contract, largely felt to be a stopgap measure while the younger Steelers' defensive ends developed a bit more.

If this is the end of the line for No. 99, he has left an impressive legacy, including a reasonably solid game against the Saints.

The team drafted Stephon Tuitt in the second round with the thought he would soon improve to the point he can start opposite Cameron Heyward on the Steelers' defensive line. Tuitt's run-defense hasn't gotten to the point yet where he can be counted on in the base defense, but now it's no longer an option to postpone his development. He will likely get a start next week against Cincinnati, or rotate heavily with Cam Thomas against the Bengals in a must-win game.
