Bills wide receiver/returner Percy Harvin has been placed on the non-football illness list, effectively ending his season and potentially his career for the second time, the club announced on Monday.

Harvin, 28, was lured out of retirement back in November, appearing to be fully healthy. Though, through two games, the former first-round pick has two receptions for six yards and no touchdowns. The Bills report his migraine headaches have returned, something that has plagued his eight-year career.

"He was doing whatever he could to try to play, but I don’t know if that was in his best interest,” said head coach Rex Ryan via the official team website. “We were trying to make sure he’s well.”

The Bills signed him out of desperation when their wideout corps was depleted by injuries. The team indicates Harvin will mull retirement for a second time.

Harvin was initially thought to be a lock to return back in April. but decided to retire instead. The 5-foot-11, 184-pounder is well-traveled since arriving in the league in '09, spending his first four seasons in Minnesota. After a shocking trade sent him to Seattle in exchange for three draft choices, Harvin would last just six regular season games for the 'Hawks due to a barrage of injuries and dustups with former teammates in two seasons.

Harvin would return in time for the Seahawks' 2013-14 Super Bowl championship, taking a kickoff to the house versus the Broncos. Though, midway through the 2014 season, Harvin was traded to the Jets.

His availability on the field his whole career has been inconsistent, as he's played in just 75 regular season games during his eight-year stint in the league.
