Angels manager Mike Scioscia said before Wednesday's series finale at Oakland that Weaver was back in the Los Angeles area to have his arm checked by Dr. Lewis Yocum. With an off day Thursday, each pitcher could slide up a day in the rotation on regular rest.
Weaver was struck on the right arm by a line drive from Dustin Ackley's bat in the fifth inning of his loss Sunday at Seattle. He has not thrown since.
Weaver is 16-4 with a 2.86 ERA this season. He also pitched a no-hitter against Minnesota on May 2.
