After coming out of retirement to help bolster the Bills ailing receiving corps, Percy Harvin's return to football lasted just two games.
The Bills announced on Monday Harvin was placed on the Reserve/Non-Football Illness list and will miss the final four games of the 2016 season.
The former Florida star missed Sunday's 38-24 loss to Oakland with migraine headaches.
For the year, Harvin caught two passes for six yards. He also had one rush for 11 yards.
After signing with the Bills at the start of the 2015, lingering knee and and hip injuries forced Harvin into retirement.
He played five games and caught 19 passes for 218 yards and a touchdown last season.
