FORT MYERS -- Twins closer Joe Nathan said Sunday morning that he will return to Minnesota for an MRI exam on his surgically repaired right elbow.

Nathan left Saturday's game against Boston with the injury and came back Sunday morning feeling continued soreness and stiffness in the elbow.

Nathan, 35, had surgery Oct. 20 to remove bone spurs and other loose particles from the elbow. He hopes and the team hopes that what he's experiencing is the breaking up of scar tissue in the elbow.

"We're going to get some pictures just for some peace of mind," Nathan said.

Nathan said he would have taken a couple days off from throwing anyway, so he'll get the elbow looked at, comparing this MRI exam with one that he had before undergoing surgery.
