Simms, who was undrafted out of Tennessee, first signed with the Green & White after a successful tryout at the 2012 rookie minicamp. He was a final cut that summer but was signed to a reserve/future deal on Dec. 31, 2012, then made the 2013 roster as the first backup to rookie starter Geno Smith.
Simms played in three games in '13 and threw for his first pro touchdown in Week 11 at Buffalo. He returned last season as the second backup behind Smith and Michael Vick and played in one game in Week 9, filling in for a shaken-up Vick in the fourth quarter at Kansas City.
