SURPRISE, Ariz. -- Outfielder Josh Hamilton, who played just 89 games last year because of injuries, left Wednesday's first full-squad workout with a bruised left shoulder.

Hamilton injured the shoulder when he took a tumble chasing after a popup during morning outfield drills. He was taken to the Rangers' training room to receive treatment but there are no plans yet to send him for an MRI. He is listed as day-to-day.

"Dr. [Keith] Meister looked at him and didn't think there was anything structurally wrong," Rangers assistant general manager Thad Levine said. "We'll take a look at it again in the morning and see what we're dealing with."

Hamilton was on the disabled list last year from April 25 to May 12 with a bruised rib-cage muscle and again from June 1 to July 6 with a torn abdominal muscle that required surgery. He also missed time in September with a pinched nerve in his lower back.

He does not believe this is serious, but the Rangers took him out of the workouts as soon as the injury occurred.

"I got a spasm in there and in my neck," Hamilton said. "I don't see it being a problem. I just fell over and fell on my shoulder."

He is the second key Rangers player to suffer an injury during drills in camp. Pitcher Derek Holland sprained his right knee on Saturday during agility drills.

Holland had an MRI on Monday that confirmed the original diagnosis of a sprained knee. He was scheduled to resume throwing on Wednesday.

The Rangers also announced that Minor League pitcher Omar Poveda will have Tommy John surgery to repair a torn ulnar collateral ligament in his right elbow. Poveda has been throwing in camp but came down with some discomfort in his elbow. He had an MRI on Wednesday that showed a complete tear in the ligament.

Poveda, who was added to the 40-man roster this winter, was 11-5 with a 4.14 ERA in 22 games with Double-A Frisco last season.
