The Washington Redskins have promoted rookie wide receiver Aldrick Robinson to the 53-man roster according to a person with knowledge of the situation.

Robinson was the Redskins’ final 2011 draft pick on the practice squad. Ten of the other 11 have made it to the 53-man roster this season, although receiver Leonard Hankerson’s season ended in injury.

Robinson, whom Washington drafted in the sixth round out of Southern Methodist University, spent the entire season on the practice squad, but will get the opportunity to compete for playing time in the season finale at Philadelphia on Sunday.

The 5-foot-10, 184-pound Robinson has great speed. He clocked a 4.35-second 40-yard dash at the NFL combine. At SMU, he recorded 81 receptions, 3,314 yards (fifth in SMU history) and 30 touchdowns for the Mustangs over a four-year career.

He averaged just more than 16 yards per catch for his career, and as a senior, Robinson recorded 65 catches for 1,301 yards and 14 touchdowns. His 20-yard-per catch average ranked sixth in the nation, and his 14 touchdowns tied for fourth.

Robinson struggled during the preseason and didn’t make the final roster cut, but was re-signed to the practice squad.

The team has veterans Santana Moss, Jabar Gaffney, Donte Stallworth, David Anderson and second-year wideouts Anthony Armstrong, Brandon Banks and Terrence Austin, as well as rookie Niles Paul on the roster.
