Ryu also served a 15-day stint with a right gluteus strain. The fact he was able to bounce back from both injuries -- without a drop-off in results -- is encouraging, Ryu said.
"It helps to know that both times I came back in the regular season, I had good games," he said through a translator. "I'm encouraged by that, and I see it being no different this time around."
Ryu will throw three innings Wednesday, with 15 pitches per inning. He went 14-7 with a 3.38 ERA over 152 innings in his second Major League season.
If healthy, Ryu will likely slot into the No. 3 spot in the the Dodgers' playoff rotation, behind right-hander Zack Greinke. However, manager Don Mattingly has not yet announced his rotation beyond Game 1 starter Clayton Kershaw.
