Deion Sanders signed a one-year, $1.5 million contract with the Baltimore Ravens on Wednesday, after passing his physical. Sanders, who returned to football with the Ravens last season after three years out of the game, attended practice earlier Wednesday but didn't participate as he hadn't yet been medically cleared. He underwent surgery in the offseason on one of the toes on his left foot. His return to the team was delayed for several days while his orthopedic surgeon in New York examined Sanders and reviewed the results of an MRI of the foot. The seven-time Pro Bowl cornerback, who will turn 38 on Aug. 9, could earn as much as $4 million if playing-time incentives are triggered. Sanders, playing primarily as a nickel back, finished second on Ravens last year with three interceptions. He was limited to nine games because of his toe and hamstring injuries.
