Angels manager Mike Scioscia said Tuesday that "nothing's changed" with Weaver, who was hit by a Dustin Ackley liner in the fifth inning against the Mariners on Sunday and was taken out one inning later.
"We'll get some clarity here," Scioscia said, "but from where we talked yesterday, nothing's changed."
And that's part of the problem. Weaver, originally lined up to start Friday's series opener against the Tigers, has yet to throw and spent most of Tuesday afternoon in the trainer's room at Oakland Coliseum, eventually coming out with ice on a shoulder Scioscia called "a little tender" on Monday morning.
Nothing's official yet, but if Weaver doesn't pitch this weekend, it would probably be Ervin Santana starting Friday, C.J. Wilson going on Saturday and Zack Greinke pitching Sunday's series finale, the Angels at least having the benefit of a Thursday off-day to keep everyone on normal rest.
The Angels were originally counting on Weaver, 16-4 with a 2.86 ERA, to make six more starts in September, getting very little extra rest in between in order to maximize the ace right-hander's usage down the stretch.
As part of their final slate of September callups on Tuesday, the Angels surprisingly added Minor League starter Barry Enright to the roster, along with catcher Hank Conger. Enright can provide some necessary depth in case Weaver has to miss time.
"We have to get more information before we can determine whether he's doubtful or not," Scioscia said. "Nothing's changed from yesterday when we talked."
