E.J. Gaines

Gaines previously chose to opt out of the 2020 season altogether. His departure likely keeps fourth-year corner Levi Wallace pinned across from All-Pro Tre'Davious White. Oft-injured, Gaines has made just six appearances over the past three seasons.

Gaines spent last year out of the league after getting waived with an injury settlement. He re-signed with Buffalo in March and had an inside track to a roster spot. With Gaines sitting out, Cameron Lewis, Dane Jackson, and Ike Brown will compete for depth roles on the outside.

The ex-Ram started 11 games for the Bills in 2017. His playing time has fallen ever since, with Gaines making just six appearances over the past two seasons. He tried to make the Bills out of training camp last year but ended up on injured reserve with a groin issue before getting cut loose with an injury settlement. Coach Sean McDermott's staff clearly likes Gaines, but his recent NFL history suggests he will not make the 53-man roster. 

Gaines was released off injured reserve by the Bills with an injury settlement in mid-August, but it appears he's now healthy two months later. The 27-year-old played only six games with the Browns last season and recorded 13 tackles.
