Steelers' Brandin Echols: Being evaluated for concussion

Echols is being evaluated for a possible concussion and is questionable to return to Sunday's matchup with the Ravens, Alan Saunders of SteelersNow.com reports.

Echols took a blow to the head in the second half of the contest, and his status for the rest of the game is now in question. In his absence, Asante Samuel is a top candidate to see added work at cornerback versus Baltimore.
