Angels right-hander Garrett Richards suffered a torn left knee patellar tendon after stumbling while covering first base during Wednesday night's game, the team announced. He will have surgery next week. The recovery time is 6-9 months.
Richards, 26, had to be carted off the Fenway Park field after the stumble. The 6-9 month recovery time means he may not be ready in time for the start of spring training and potentially Opening Day 2015.
In 26 starts and 168 2/3 innings this year, Richards is 13-4 with a 2.61 ERA. He will likely receive Cy Young votes after the season. Richards has emerged as the team's ace and losing him is an enormous blow.
The Angels are already without lefty Tyler Skaggs, who recently underwent Tommy John surgery. Veterans Jered Weaver and C.J. Wilson will have to lead the staff going forward.
