Ronny Cedeno left Monday's game against the Diamondbacks after he was hit in the helmet by a Heath Bell fastball in the bottom of the seventh inning. Padres manager Bud Black said after the game that Cedeno was dealing with a bit of a headache and will be monitored overnight. He'll almost certainly be tested for a concussion. The veteran infielder is hitting .268 with three home runs and 21 RBI in 38 games since joining the Padres.
