EDEN PRAIRIE, Minn. (AP) -- Minnesota Vikings right guard Anthony Herrera is recovering from shoulder surgery.

Coach Brad Childress revealed the operation Thursday, a day after it was performed, saying Herrera had already begun his rehabilitation and will have "a maximum amount of time to recover."

Childress added Herrera "should be close" to ready when the strength and conditioning program begins in April.

Herrera started all 16 games this season, playing through his injury. Childress declined to give details of Herrera's condition or procedure, but indicated it was a major surgery.

Fellow offensive lineman Artis Hicks will have surgery Friday to repair a tear in the triceps muscle in his right arm.
