Corey Kluber has a mild quadriceps strain and will be sidelined for 7 to 10 days, an MRI has confirmed.

The timetable could cause the Cleveland Indians to delay Kluber's first postseason start.

The Indians will open the playoffs on Oct. 6.

"It's obviously not the best possible news, but it is a heck of a lot better than it could have been," Terry Francona said. "This will give him a chance to rest up and hopefully throw a couple bullpens. In the long run, that could help him."
