PHILADELPHIA -- Wednesday's seventh inning took its toll on the Cubs.
Dioner Navarro left the field on a cart after he was on the receiving end of a hard collision at the plate with the Phillies' Chase Utley. Navarro hung on to the ball and Utley was out, but the catcher's right leg was caught under him.
X-Rays came back negative on Navarro's right ankle, and the injury was being evaluated as a contusion. The Cubs don't know when he could return, but after the game, they said Navarro was day to day.
"He was able to do some things, squats and things like that, so we're looking a little better than we thought," manger Dale Sveum said after the game.
While the lack of a fracture is good news for the Cubs, they still only have one other catcher -- Wellington Castillo -- on their 40-man roster. Sveum said they would take more time to evaluate Navarro before they made any roster moves. The manager called Navarro -- who is hitting .284 in 61 games this season -- the "ultimate backup catcher."
The Cubs will have to make at least one move, however. Outfielder Thomas Neal dislocated his right shoulder while making a throw in the seventh inning, and the team placed him on the disabled list after the game.
Neal, who was claimed off waivers from the Yankees on Monday, was perplexed by the injury, and both he and Sveum said they had never seen anyone dislocate their shoulder on a throw.
"As soon as I released it, I knew something was wrong," Neal said. "It kind of felt like a dead arm, almost."
Neal's shoulder popped out of place after John Mayberry Jr. doubled down the left-field line. Neal rushed over to make a play and tried to throw Mayberry out at second. Neal said he attempted to make the throw a little quicker than normal, which may have led to the injury.
"I just wanted to get it out as quick as possible," Neal said with his right shoulder heavily wrapped in ice. "I made the throw and here we are."
