Just a few weeks after reporting to spring training camp and expressing confidence that his recent health issues are behind him, second baseman Brian Roberts is again dealing with back pain.

Roberts, who has been sidelined since Monday after experiencing back spasms, had "trigger-point injections" Friday and is scheduled to have an MRI on Saturday.

"We don't know. We'll just have to see," Orioles president of baseball operations Andy MacPhail said. "Fortunately, this is a doctor that he saw last year. We had plenty of MRIs from last year. We'll take a look this year and see if there are any changes. It's not my preference, but these are things you just have to deal with. It's March 11. You just don't know how they are going to unfold. You just have to take the proper medical precautions and move from there. There's no sense fretting about what it could be, might be. Just let the doctors do their stuff."
