PHILADELPHIA (AP) Eagles rookie cornerback JaCorey Shepherd will have an MRI on Monday to determine the extent of a right leg injury suffered in Sunday's open practice.

Shepherd was injured when he ran into Darren Sproles after a play near the sideline. He stayed down for a few minutes before being carted off the field.

The sixth-round pick from Kansas saw action with the first unit at nickel cornerback. The Eagles are looking for a cornerback to take that starting spot after trading Brandon Boykin last week.
