McDonald goes on 49ers’ physically unable to perform list, team releases Huners

49ers place McDonald on PUP list, release Huners

SANTA CLARA, Calif. — The San Francisco 49ers placed defensive end Ray McDonald on the active physically unable to perform list Friday, an expected move as he recovers from offseason knee surgery.

The team also released guard Matthew Huners one day before the first day of practice in coach Mike Singletary’s first training camp in charge and signed guard-center Matt Spanos to a one-year deal.

McDonald hurt his right knee last Oct. 19 against the New York Giants and underwent reconstructive surgery on the anterior cruciate ligament.

On Thursday, the 49ers signed defensive lineman and former Stanford star Babatunde Oshinowo to a one-year deal to give them some added depth while McDonald is sidelined. A third-round draft pick by the 49ers in 2007, McDonald has played in 24 career games and has 30 tackles and 2.0 sacks.

Spanos, a former collegiate star at Southern California, was released by the Dallas Cowboys on July 2. He broke into the league as an undrafted free agent with the Miami Dolphins last year before his release on Aug. 30, 2008.

Huners signed with the 49ers as an undrafted free agent on April 30 out of South Florida.
