Ruiz said X-rays were negative, but he will see team doctors Monday in Philadelphia.
"I hope so, yeah," said Ruiz, if he thinks he will be OK to play Wednesday in Game 1 of the National League Division Series. "We'll see [Monday] when I wake up, but right now, it's sore."
Ruiz finished the season hitting .302 with eight home runs and 53 RBIs in 121 games. His average ranks eighth in club history among catchers with 400 or more plate appearances. His .400 on-base percentage tied for first. Andy Seminick had a .400 OBP in 1950.
"He had a big season, man," Phils manager Charlie Manuel said. "Like I've said for about a month, the last two years, Chooch has really improved his game -- defensively and offensively. He's become what I call a complete catcher. I'm happy for him. I'm proud of him."
