The righthander has an issue with his neck, the left side of his neck to be specific. So his start was pushed back. If Matsuzaka throws in the bullpen today or Saturday, he could make a start for Pawtucket on Monday.
According to Bobby Valentine, Matsuzaka is scheduled for two more starts in the minors — with a third possible.
Matsuzaka has made two rehab appearances so far as he makes his way back from Tommy John surgery.
In other news:
• Josh Beckett said his right lat is feeling a lot better. His start on Saturday will be skipped but he threw today and felt fine. He is on track to start next week.
Beckett said his lat was bothering him before his start in Chicago on Sunday and in retrospect he should have spoken up. Valentine agreed, saying that would have been good to know.
• Valentine, David Ortiz and virtually every other player expressed support for injured Yankees closer Mariano Rivera. Valentine said Rivera is one of the best people he's ever met. "Never heard a bad word about him and if you've ever been a reliever, he was the pitcher you looked at," Daniel Bard said.
• Aaron Cook has No. 35.
• Cody Ross picked up a bunch of t-shirts from the El Pelon Taqueria near Fenway Park and gave them to Alfredo Aceves, Dustin Pedroia and Kevin Youkilis. He also kept one for himself. Why? El Pelon means "The Bald Guy."
