Daisuke Matsuzaka placed on 15 day DL by Red Sox

Daisuke Matsuzaka has been placed on the 15-day disabled list, Red Sox manager Terry Francona said Sunday, and he hinted it could take months for the struggling righthander to recover.

"It's not going to be a two-week DL thing," said Francona. "We have a lot of work ahead of us to get him back to being Daisuke."

Matsuzaka had an MRI done yesterday that showed "a little bit of weakness in his shoulder," but there is no true structural damage.
