Daisuke Matsuzaka may not make his next start for the Red Sox after failing to get out of the second inning against the Blue Jays on Saturday night.

"I'm not sure," Bobby Valentine said. "Going to see. Have some meetings here with him, too. He was very disappointed yesterday. So was I."

Matsuzaka has been unable to get through the fourth inning in three of his last four starts. He is 1-5 with a 7.20 earned run average on the season.
