The San Francisco 49ers have released defensive lineman Darnell Dockett and five other players.

The 49ers also released linebacker Philip Wheeler, safety Craig Dahl, offensive linemen Joe Looney and Patrick Miller, and receiver Issac Blakeney on Friday to leave 69 players on the roster. San Francisco needs to cut down to 53 by Saturday.

Dockett was one of the more prominent free agents added by San Francisco this offseason but he was unable to do enough to make the team. Dockett missed all of last season in Arizona with a knee injury and sat out Thursday's exhibition finale with injured ribs.
