Sosa (hamstring) was placed on the 10-day injured list due to a strained right hamstring, Scott Lauber of the Philadelphia Inquirer reports.
After being removed from Thursday's loss to Miami while walking with a noticeable limp, Sosa was officially diagnosed with a strained hamstring Friday. No timetable has been put in place for his recovery, but a return in the minimum 10 days would allow him to see action again before the end of the season.
