PITTSBURGH — Bud Dupree slammed the turf in anger, well aware of what the pain in his right knee meant.

One bad step in the fourth quarter against Baltimore on Wednesday put an end to the Pittsburgh Steelers linebacker's season. Maybe his time with the only franchise he's played for, too.

Dupree suffered a torn ACL in the 19-14 win over the Baltimore Ravens Wednesday afternoon.

Dupree had eight sacks this season after recording 11 last season. He has 34.5 career sacks and will be a free agent after the season.
