Here's Tony Jackson's initial report for ESPNLosAngeles.com:
Jon Garland left Wednesday's Cactus League game with two outs in the top of the second inning because of a left-oblique injury. There was no immediate diagnosis or prognosis, but Garland said he would meet with a team doctor either later in the day or early Thursday morning.
Garland said no actual tests have been scheduled, but that, "I'm sure they are going to want to do that."
Garland, whom the Dodgers signed in November to a one-year, $5 million contract with an $8 million club option for 2012 to be their fifth starter, was making just his second start of the spring. After throwing the first pitch to Seattle Mariners shortstop Josh Wilson, his 30th pitch of the game, Garland knelt down on the front of the mound, stood back up and immediately made a gesture toward the dugout to summon trainer Stan Conte.
Garland then walked around the mound for a minute or two while clutching his left side before ultimately walking off the field with Conte. ...
Bill Shaikin of the Times wrote that "although the Dodgers have not identified the problems, his actions were consistent with an oblique injury, which can require a month or more of recovery."
With Vicente Padilla out, the leading candidates to replace Garland if he's out of the rotation for the start of the season would be Tim Redding and John Ely.
