Phillies right fielder Bryce Harper stuck out with the bases loaded in the seventh inning of Sunday'as loss to the Blue Jays and did not return.

The team is calling it lower back stiffness.

"He'll get a lot of treatment and we'll cross our fingers," Phillies manager Joe Girardi said after the game.

Harper walked back to the dugout and appeared to tell Girardi that he was no longer able to play, and then packed up his stuff and walked down the tunnel back to the Phillies clubhouse.

The 27-year old is hitting .267 with 11 home runs with 28 RBI.

The Phillies have seven games left and are currently the top team in the NL wild card race making them the No. 7 seed as of now.
