The Marlins officially haven't told Logan Morrison he's moving to first base. He's prepared to transition from left field back to his natural position. The pressing question is when Morrison's surgically repaired right knee will allow him to do so.

Speaking Saturday morning prior to the third annual LoMo's Camp For a Cure to benefit the American Lung Association, Morrison could not say with any certainty. The Marlins' first full squad workout in Jupiter is about a month away and Morrison has yet to run, hit or throw.

"I'm not going to be able to run until the middle of February," he said. "It'll take a week into spring training, then it will be a progression to lead up to bases at some point. I don't know when that will be."

Morrison in early September underwent a procedure to repair the patella tendon. It was a bit different than the debridement surgery he had on the same knee in December 2011. This was a full repair, requiring a longer incision and drilling a hole into the knee cap to attach the tendon.

The knee never felt right after the first surgery. Morrison as a result missed much of spring training and when he did get on the field play through persistent pain. The result was a .230 batting average and a .707 on-base plus slugging percentage in 93 games (236 at-bats).
