Clay Buchholz goes to the disabled list with a sore elbow, but he doesn’t need surgery:

Clay Buchholz was somber in his tone and frustrated by his sore right elbow, but tried to stay optimistic on Saturday afternoon after learning that his ulnar collateral ligament has no structural damage. At this point, surgery seems unlikely.

Buchholz will go on the 15-day disabled list and rest his arm for at least a week before throwing again. The Red Sox called up left-handed starter Brian Johnson, one of the team’s top prospects who had been lights-out in Triple-A Pawtucket this season.

“The All-Star break coming, it gives us a few days to rest and from all the facts I’ve gathered, that’s what it’s going to be, it’s going to be rest,” Buchholz said. “Had an MRI last night and the UCL, as it was when I was told five years ago when I had an MRI, it looks like my UCL [is one] that’s never thrown a baseball before, so that’s good. What’s going on here is just something that’s going to take a week off of throwing or 10 days off of throwing and then get back into it.

So this injury puts a cramp in the Red Sox attempted comeback, and possibly takes Buchholz off the trade market. It doesn’t look like it will be season ending, however.
