The Buffalo Bills announced that the team signed linebacker Blake Costanzo on Friday.
Costanzo originally joined the Bills’ practice squad in 2007. He was promoted to the 53-man roster for the final three games last season.
Costanzo returns to Buffalo following his release on Aug. 30. A Lafayette College product, Costanzo originally entered the NFL as an undrafted free agent in 2006 with the New York Jets.
