Rojas was removed from Tuesday's Game 3 of the NLDS due to a leg injury, Alden Gonzalez of ESPN.com reports.
Rojas has been playing through an adductor injury since September, and he seemed to aggravate it while running the bases in the third inning Tuesday. If the 35-year-old infielder is forced to miss any additional games, Tommy Edman would likely move to shortstop while Andy Pages fills the gap in center field.
