The Buffalo Bills signed a pair of veteran offensive lineman: Antoine Caldwell and Tony Hills.

Caldwell is a former Houston Texans third-round draft pick who started 19 of 39 career games.

He played collegiately at Alabama where he was a two-time captain.

Hills is a former Pittsburgh Steelers fourth-round draft pick from Texas.

He has played for the Steelers, Denver Broncos and Indianapolis Colts.

Both players should add quality depth to the Bills' offensive line.
