TORONTO -- Yankees utility man Jayson Nix has been sent to New York for an MRI exam after feeling soreness in his left hip flexor.
Manager Joe Girardi said that Nix suffered the injury while fielding a ground ball on Thursday against the Blue Jays but did not mention it to the club's staff until Friday. He will rejoin the team in New York.
"For us to send him back and get an MRI, there's a concern," Girardi said.
With Nix unavailable, Eduardo Nunez started at shortstop for the Yankees on Saturday, with Derek Jeter getting a half-day as the designated hitter.
If Nix is out for an extended period, Nunez would be the Yankees' primary backup infielder. He worked out on the field early on Saturday morning with coaches Mick Kelleher and Tony Pena, taking extra ground balls.
"There's a possibility we may not have [Nix] for a while, and that's why Nuney becomes all the more important," Girardi said.
