Eagles' Aaron Grymes: Sprains shoulder on Thursday

Grymes (shoulder) injury has been identified as an AC joint sprain and could sideline him or the rest of the preseason, Les Bowen of the Philadelphia Daily News reports.

Analysis:

Grymes left Thursday's game early with what was at the time an unknown injury. He was currently running with the third-team defense, and will look to resume that role when he returns. His absence leaves the Eagles with four cornerbacks currently sidelined, allowing Randall Evans, C.J. Smith, and Denzel Rice to see significantly more reps for the time being.
