The Steelers yesterday signed 6-4 wide receiver Walter Young from their practice squad to their 53-man roster and released linebacker Marquis Cooper.

Wide receiver Hines Ward has been listed as questionable all week with a hyperextended knee although he did practice on Friday. Young's signing could be as insurance in case Ward cannot play in Baltimore today.

Cooper, a third-year pro, was signed Oct. 31 when linebacker Arnold Harrison was placed on injured reserve.
