Thomas was just released yesterday to make room for RB J.D. McKissic who was claimed off waivers by the Lions.
The timing also allows Bryant to be eligible to be designated to return from injured reserve starting Week 9.
Thomas, 27, is a former fourth-round pick of the Cardinals back in 2014. He lasted just over a year in Arizona before he was waived and later claimed by the Dolphins.
Thomas was in the third year his four-year, $2,652,092 rookie contract when the Dolphins waived him in 2017 and he was later claimed by the Giants. He had a brief stint with the Lions after he made the decision to convert to tight end and later caught on with the Bills.
Buffalo declined to tender Thomas a restricted offer this offseason and he later signed on with the Lions.
In 2018, Thomas appeared in 12 games for the Bills and caught 12 passes for 77 yards receiving and no touchdowns. Pro Football Focus had him rated as the No. 64 tight end out of 70 qualifying players.
