Dodgers pitcher Hyun-Jin Ryu is scheduled to throw a bullpen session in the next couple of days and possibly as early as Sunday, according to the L.A. Times.

Ryu, who is currently on the 15-day DL with a shoulder injury, remains without a timetable for his return to the pitching staff. He has been unable to throw in a game so far this season after posting a 14-7 record in 2014 with a 3.38 ERA and 139 strikeouts.
