Ryu (shoulder) had an MRI Monday that revealed no structural damage in his left shoulder, and the left-hander has not been ruled out from making one more regular season start in advance of the playoffs, the Dodgers' official site reports. Probably the best news the team could have expected. Ryu received a cortisone injection, and depending on how he recovers, he could be available as early as September 22 when the Dodgers take on the Giants.
