Boston Red Sox righthander Daisuke Matsuzaka will skip his next turn in the rotation Thursday because of weakness in his right shoulder.

Manager Terry Francona said last night that an MRI exam showed no structural damage, though there was a weakness.

Matsuzaka, the World Baseball Classic MVP, is 1-5 with an 8.23 ERA.

Chavez sidelined. Seattle Mariners outfielder Endy Chavez is done for the season after an exam revealed a serious right-knee injury suffered Friday night in a collision with shortstop Yuniesky Betancourt.

Elsewhere. Texas reinstated closer Frank Francisco (shoulder tendinitis) from the disabled list. . . . Cincinnati shortstop Alex Gonzalez returned to the 15-day DL with bone chips in his throwing elbow. Kansas City sent righthander Kyle Davies to triple-A Omaha and activated reliever Robinson Tejeda, a former Phillie, off the 15-day DL. . . . Emilio Navarro, who at 103 is believed to be the oldest living professional baseball player, threw out the first pitch before the Oakland-San Diego game last night. Navarro was the shortstop and leadoff hitter for the Cuban Stars of the Eastern Colored League in 1928 and hit .337 the following year.
