Boston Red Sox trade deadline acquisition Kyle Schwarber has experienced a minor setback in the rehabilitation of his right hamstring strain, as he now has a left groin strain as well, according to Jen McCaffrey of The Athletic.

“Sources confirm Kyle Schwarber has suffered a minor setback with a left groin strain in the midst of his rehab from a right hamstring strain. The setback isn’t expected to significantly delay his timetable for return, but nevertheless is concerning.”

While the setback isn't expected to significantly delay Schwarber's debut for the Sox, it will push it back a while as the Red Sox have lowered his activity level as a precaution.

This news comes during the worst stretch of the season for the Red Sox as they are 2-8 in their last 10 games and have relinquished their AL East lead to the Tampa Bay Rays and the New York Yankees now only sit two games behind them.

So far this season Kyle Schwarber has had a slash line of .253/.340/.570 for an OPS of .910, which is easily the best season of his career thus far. The Red Sox were looking to utilize Schwarber at the first base position but with these two injuries, and first base being a position that requires a lot of stretching, that is looking less and less likely.

The Red Sox hope that Schwarber will be an impact player at the end of this season for their playoff run, but for now, they will just have to wait for him to heal.
