Lopez (shoulder) will resume bullpen sessions this week, Christina De Nicola of MLB.com reports.
Lopez has been out for the entirety of the second half while battling a shoulder strain. He made one three-inning rehab appearance back on Aug. 21 before the Marlins elected to slow him down. He still seems to have time to make it back for at least a start or two before the end of the season, but he may not be fully stretched out, and even a small setback could see him shut down for the season with less than four weeks remaining on the schedule.
