Jason Sehorn’s return to the Rams ended just hours after it began. Sehorn failed a team physical on Wednesday, voiding the one-year deal he signed with the team late Tuesday. Sehorn fractured a bone in his left foot in training camp last year. He underwent surgery last July, and returned for the Rams final 10 regular season games. Sehorn had additional surgery in February. Rams head coach Mike Martz said after the second surgery, Sehorn’s foot hadn’t healed as well as the team hoped.
