Percy Harvin's comeback with the Buffalo Bills lasted only a little more than a month.
The veteran receiver came out of retirement to sign with the team Nov. 1, but on Monday the Bills placed him on the non-football illness list due to a recurrence of the migraines that have plagued him throughout his career.
Harvin, 28, was active for two games -- and caught two passes for 6 yards in one of them -- before he again began having severe headaches that held him out of Buffalo's past two games, according to the team's website.

"He was doing whatever he could to try to play, but I don't know that was in his best interest," Bills coach Rex Ryan told reporters last week. "We were trying to make sure he's well."
Harvin blossomed into one of the league's top receivers and return men while with the Vikings from 2009-12, but injuries and health problems have limited him to only 21 games for the Seahawks, Jets and Bills in the past four seasons.
