White Sox manager Will Venable said Monday that Murakami (hamstring) stayed back in Chicago during the team's road trip and was given a platelet-rich plasma injection, James Fegan of SoxMachine.com reports.
Murakami landed on the 10-day injured list Saturday and is expected to miss 4-to-6 weeks of action with a Grade 2 right hamstring strain. The hope is that the PRP injection helps aid the healing process, but he will be sidelined several weeks regardless.
