Following his MRI exam, Jonathan Broxton is headed for the disabled list, with Kenley Jansen making his trip to Chattanooga a mere layover on his way to New York to replace Broxton on the active roster.

There were different ways to interpret the news that an MRI revealed Jonathan Broxton had, according to the Times, a bone spur but no structural damage. On the one hand, the pain caused by the bone spur could account for Broxton’s awkward appearance Tuesday and even his rough-and-tumble 2011, but it wouldn’t seem to add much to a physical explanation of why he’s been so off his game since mid-2010 — unless it has been a recurring problem.

We’ll undoubtedly hear more on this as the day progresses.

Update: Broxton could be out for a month, according to Ken Gurnick of MLB.com:

… Broxton said he was told he would be shut down for two to three weeks to allow dissipation of fluid in the joint, then resume throwing. He said also had a pre-existing bone spur in the back of the elbow that showed up in a 2010 MRI, but that wasn’t the cause of his latest trouble. …

He was examined by team doctor Neal ElAttache, who told him the injury was probably the result of his joint opening and closing at high velocity “and the bones slam against each other. It takes a while to get the fluid in there.”

He said he was told he could take three or four days off and continue pitching, but the best course of action would be to shut down and let the bruise completely heal. Broxton said he didn’t think this injury was related to his second-half collapse last year.

“It probably started in the spring and caught up to me now,” he said. “The ligament is fine, there are no chips or anything. It’s just bruised.” …

After writing that Wilson Betemit should have let himself get hit by a pitch with the bases loaded, Kansas City Star sportswriter Lee Judge decided he should step up and see what it would be like. The video is pretty great.
