After three more weeks of consideration, Dallas Cowboys quarterback Tony Romo is leaning more toward undergoing a Mumford procedure on his left clavicle than attaching a plate over the mending collarbone, according to a source.

The Mumford procedure is where a portion of the distal clavicle is shaved off or removed.

Romo, however, has yet to make a final decision on the type of surgery he will have in March as he continues to gather facts and evaluate the benefits of each procedure that he's discussed with doctors.

"We don't have a final [decision]," Cowboys executive vice president Stephen Jones said Tuesday morning from the NFL scouting combine in Indianapolis. "Obviously that's something that he'll decide to have it or not decide to have it. It's preventative type surgery, and I think he's wanting to make sure if he does do it it's the right way to do it."

The Mumford procedure has been the preferred option, sources told Staff Writer David Moore earlier this month, because it places less long-term stress on the collarbone than attaching a plate. That approach is taken to reduce pain and discomfort where the clavicle meets the shoulder.

The other option, using a set of screws to attach a plate over Romo's left collarbone to limit the potential of fracturing it to become a recurring issue, isn't as ideal.

Both procedures have a six to eight week recovery period, which would clear Romo to take the field for the start of organized team activities in May.

Romo fractured his left clavicle on two separate occasions in a span of 10 weeks, limiting him to four games last season. He has broken his left collarbone three times since the 2010 season.
