The NCAA has waived the mandatory one-year waiting period for offensive lineman Shane Callahan, who transferred to CU Boulder from Auburn University in July, meaning the sophomore will be eligible to compete during the 2014 season.

The timing couldn't be better: CU is in need of replacing two starting offensive lineman who completed their eligibility in 2013.

The school — which learned of the decision Monday afternoon — had requested he be eligible to compete this season based on undisclosed family reasons, a team news release said. Callahan participated in preseason practices Saturday.

"We're happy for Shane and his family that the NCAA declared him eligible to play this year," MacIntyre said in a statement of the 6-foot-6, 300-pound player. "It's great to have another state of Colorado athlete on our football team."
