Morel (oblique) is expected to begin a rehab assignment at Triple-A Jacksonville during the upcoming week, Kevin Barral of FishonFirst.com reports.
The 26-year-old was given an estimated timeline of 4-to-6 weeks when he landed on the injured list in late March, and Morel looks to be eyeing a return near the short end of that window with a shot at activation before the end of April. Once he's reinstated, Morel may face competition for starts at first base from Connor Norby, though Norby could also move across the diamond and unseat the struggling Graham Pauley as the Marlins' primary third baseman.
