The Cowboys have found a lot of ways to attack the Eagles defense early in their Sunday night game, and things might be a little easier for them now that starting safety Reed Blankenship has left the game to be evaluated for a concussion.

Blankenship left the field under his own power, but was then evaluated in the medical tent before going into the locker room. Prior to leaving the field in the middle of the second quarter, the safety recorded three total tackles.

Rookie Sydney Brown stepped into Blankenship’s role, just as he did earlier in the season. Fortunately, Brown has had a smattering of experience throughout the season due to the various injuries throughout the secondary, but he’ll be challenged by Dallas’ impressive receivers.

The Eagles have had to be versatile throughout the secondary all season, rotating guys, and only recently had a bit of stability after bringing in Kevin Byard. Blankenship has already missed time this season due to rib injuries, and hopefully won’t be someone they have to replace for very long.
