Pace told the Chicago Tribune on Friday that after the season, he would evaluate how he felt and whether or not it made sense to return for the 2010 season.
The offensive tackle, who is a seven-time Pro Bowl selection, injured his groin muscle against Minnesota on Nov. 29, and was inactive for three games before dressing, but not playing, in Monday night's overtime victory against the Vikings.
Pace told the Tribune that he misses playing, and cited that as a reason for his decision to re-evaluate at the end of the season, but added that he understood the situation.
Pace, 34, was signed after John Tait retired, and allowed only three sacks in 11 starts. Pace is under contract through 2011, according to the Tribune, and is scheduled to be paid $3.75 million next season, with a $250,000 workout bonus.
