The Angels, who have won seven of their past eight games and are 18-13 since the All-Star break, have been getting exceptional starting pitching of late. They have limited opponents to three earned runs or fewer in 10 straight games and 22 of 31 since the break.
But at the beginning of the month, they lost starter Tyler Skaggs, who last week underwent Tommy John surgery, and they have used just six starting pitchers all season. After Wednesday's game, they optioned right fielder Brennan Boesch to Triple-A Salt Lake, and they are likely to call up two pitchers to fill in for Richards, the Los Angeles Times reported.
"We have a game tomorrow," Scioscia said. "We're going to go out there and hopefully put together enough good things to win a game. We're just going to take these games one inning at a time, one game at a time. When Garrett's spot comes up in the rotation, we'll obviously have somebody ready. We have to keep moving on."
Wednesday's win increased the Angels' lead over the Oakland Athletics to 1½ games, but closing out Oakland without Richards will be a formidable task.
"It doesn't look too good, it doesn't look too good," said Weaver, noting that an Angels trainer told him he'd never seen an injury like it. "He's been that guy you count on to get you deep into games and pull out the victory.
"He was having a tremendous season. This was a crushing blow to him. Our thoughts and prayers are with him. Hopefully it doesn't turn out as [bad] as everyone thinks it is.
"We've got a great team. I think everyone will rally around this."
