Martin (forearm) was with the Rangers on Friday and could be activated for Saturday's game against the White Sox, Evan Grant of the Dallas Morning News reports.
Martin had a pair of scoreless outings while out on a rehabilitation assignment at Double-A Frisco. Aside from the game in which he sustained his injury -- four runs, four hits, two-thirds of an inning -- Martin had been a reliable arm out of the bullpen prior to his injury.
