HOUSTON — Astros right-hander Aaron Sanchez will have surgery on his throwing shoulder and will miss the remainder of the season.

Sanchez hasn’t pitched since Aug. 20 because of what the team said was a sore right pectoral muscle. The team had expected him to return this season, but general manager Jeff Luhnow said Thursday morning that he would have the unspecified procedure on his right shoulder next week and wouldn’t return this year.

Sanchez was acquired from Toronto on July 31 and combined with three relievers to throw a no-hitter in his first start for the Astros on Aug. 3.

Also on Thursday, Luhnow said that outfielder George Springer has been diagnosed with a mild concussion and will miss a few games. Luhnow said he expects Springer to return early next week. Springer was carted off the field on Tuesday after his head hit the wall after he made a catch against the Brewers.
