Pittsburgh Steelers defensive end Brett Keisel has already been ruled out for Sunday's game against the Miami Dolphins. Keisel is suffering from plantar faciitis and had a setback in last week's Thanksgiving loss to the Baltimore Ravens.
Keisel previously missed two games with the injury. He tried to give it a go in Week 13, but appears to have aggravated it. Plantar fasciitis can be extremely painful and take over a month to fully recover from. The Steelers are not giving a timetable for his return.
Before the injury, Keisel played in the first 10 games of the season, recording two sacks, 25 tackles and a fumble recovery. It will be another loss for a Pittsburgh team still clinging to slim playoff hopes.
Keisel turned 35 in September and hinted during the offseason that 2013 could be his final year. He's set to become a free agent in 2014. Keisel has spent his entire 11-year career with the Steelers and is one of the final members left from their two Super Bowl wins.
