Call fell to the ground pursuing a fly ball during Friday's game against Atlanta and was carted off the field, Mark Zuckerman of MASNSports.com reports.
While the specifics of the injury are unknown at this point, it's certainly not a good sign that Call required a cart to exit the field. The right fielder attempted to walk off under his own power but was unable to do so. With Dylan Crews already set to join the big-league roster Monday, Call's injury may have created an immediate opening in the starting nine for the top prospect to fill.
