This is a concerning issue for the Red Sox if things stay the same.

Here are the latest updates on Sonny Gray's rehab process and his projected return date.

Boston Red Sox pitcher Sonny Gray is getting an injury update, and there is some good news for Red Sox fans.

The Boston Red Sox placed right-hander Sonny Gray on the 15-day injured list on Tuesday with a right hamstring strain and recalled lefty Tyler Samaniego from Triple-A Worcester to replace him on the roster. Gray lasted just 2 2/3 innings against the Detroit Tigers on Monday, giving up one run on three hits before experiencing discomfort in his right leg. Gray, 36, is 2-1 with a 4.30 ERA in five starts this season.

The Boston Red Sox won't have Sonny Gray with the club for at least the next two weeks.

The Red Sox are making the bad news for Gray official.

Getting the Sox' No. 1 prospect in the big leagues again is the right answer.
