Long was chosen Friday at No. 78 overall.
Long was a regular starter at right guard for two-plus years for the Cornhuskers before tearing the MCL in his left knee six games into last season. Long said his knee is now fine and that will be able to take part in rookie minicamp next weekend.
Also Friday, the Redskins picked linebacker Trent Murphy of Stanford in the second round and tackle Morgan Moses of Virginia early in the third round.
