JACKSONVILLE, Fla. - A 20-year-old University of North Florida baseball player is recovering from what he believes is a shark bite.

Clayton Shulz was surfing at Jacksonville Beach.  He says the shark grabbed his foot and shook his head a little bit before letting go.

Shulz needed 400 stitches in his foot to close the wound.

He is expected to make a full recovery.
