Washington Redskins safety Will Blackmon and center Spencer Long are going through the NFL's concussion protocol after being injured in a loss Sunday to the Arizona Cardinals.

Coach Jay Gruden announced their statuses on a conference call with reporters Monday.

Blackmon's departure from Washington's 31-23 loss at Arizona meant more duty for Duke Ihenacho in the secondary. Long's departure prompted the Redskins debut of veteran center John Sullivan.

Gruden said if Long is unable to play this Sunday at the Philadelphia Eagles that the team would have to look to bring in a backup center. The Redskins will get Trent Williams back after a four-game suspension, and Gruden said the plan is for him to be back at left tackle where Ty Nsekhe played during his absence.
