Aaron Corp’s stint with the Cowboys was short. The quarterback was cut Thursday, approximately 48 hours after he signed with the club Tuesday. The move was announced along with the Cowboys’ decision to waive Brian Price, a defensive tackle who joined the organization Dec. 31. Corp, who originally entered the NFL last year as an undrafted rookie, was expected to compete for the Cowboys’ third quarterback position that was never filled last season while Price, a 2010 second-round pick by Tampa Bay, was supposed to enhance the depth of the defensive line.
