Los Angeles Angels right-hander Jered Weaver could miss his next start because of soreness in his throwing shoulder, reports Alden Gonzalez of MLB.com:

The Angels are still unclear on the status of Jered Weaver's right shoulder, manager Mike Scioscia said prior to Monday's series opener against the Athletics.

Weaver's next turn is slated for Friday, which comes after Thursday's off-day and marks the opener against the Tigers at Angel Stadium, but that's up in the air at the moment.

Weaver sustained the injury to his shoulder in the fifth inning of Friday's game against the Mariners, taking a line drive off the bat of Dustin Ackley right off the top of his shoulder. The 29-year-old right-hander has yet to undergo any tests on his shoulder and Weaver thinks it should not affect him in five days time.

Scioscia, however, said Weaver's shoulder is still "a little tender" and that the club would wait until the end of the Oakland series to make a decision on whether the Cy Young candidate should make his next start. The Angels had Weaver aligned in the rotation to line up with a possible wild card play-in game, but postponing his next start could affect that timeline.

In twenty-five starts this season, Weaver owns a 2.86 ERA and 6.8 K/9 in one hundred sixty and a third innings.
