Authorities say Minnesota Vikings running back Caleb King has been arrested on suspicion of assaulting another man.

The Anoka County sheriff's office says King was arrested Saturday.

Authorities say King assaulted a 22-year-old man, causing skull and facial fractures and cuts that required more than 50 stitches to close. The man is hospitalized in serious condition.

King signed with the Vikings as a rookie free agent last year but didn't play in a game. The 24-year-old from Liburne, Ga., is being held on a tentative charge of third-degree assault.

The sheriff's department says King assaulted the victim after the man teased King about resembling a certain celebrity.

Sheriff's Cmdr. Paul Sommer says King denies assaulting the man, saying the victim fell to the ground when King was talking to him.
