Leiter (ankle/biceps) has begun playing catch again and is expected to throw a bullpen session this weekend, MLB.com reports.
Leiter is aiming to rejoin the Rangers during the final week of the regular season as the team pushes for a spot in the postseason. The right-hander, who initially landed on the injured list in June after undergoing arthroscopic surgery on his right ankle, experienced soreness in his right biceps during a rehab assignment earlier this month.
