ORCHARD PARK, N.Y. (AP) - The Buffalo Bills have signed cornerback Johnny Adams, running back Ronnie Wingo and offensive tackle Edawn Coughman to fill out their eight-player practice squad.
Coughman spent a portion of last season on the Seattle Seahawks' practice squad. He signed with Dallas in May before being cut by the Cowboys last weekend. In 2011, the Shaw University product played nine games with Toronto of the Canadian Football League.
Wingo is an undrafted rookie free agent out of Arkansas, who was released by Atlanta last week. At Arkansas, he had 1,089 yards rushing and eight touchdowns in 49 career games.
Adams, an undrafted rookie free agent out of Michigan State, split time with Houston and Indianapolis this offseason.
Buffalo opens the season hosting New England on Sunday.
