PITTSBURGH, Oct. 15 (UPI) -- Pittsburgh Steelers defensive end Aaron Smith is done for the 2009 season because of a torn rotator cuff in his right shoulder.
Smith, 33, had been playing in pain, but when it increased during last Sunday's 28-20 win at Detroit, the team decided he needed surgery and placed him on the season-ending injured reserve list.
"He's pretty bummed," fellow defensive end Travis Kirschke told the Pittsburgh Tribune-Review. "He says it probably won't sink in until he's not out there (Sunday against Cleveland)."
Smith, a fourth-round draft pick in 1999 out of Northern Colorado, is the team's third longest-tenured player behind wide receiver Hines Ward and defensive back Deshea Townsend, and was a key component in Pittsburgh's vaunted 3-4 defense.
In five games, Smith had nine tackles (six solo) and two sacks.
He blocked field goal on Sept. 10 in a 13-10 season-opening overtime win over the Tennessee Titans.
