Vikings offensive tackle Caleb Tiernan expects to return for regular season

Minnesota Vikings rookie offensive tackle Caleb Tiernan is expected to be available for the team's regular season opener following an ankle injury. The third-round draft pick out of Northwestern missed time during the preseason after suffering the injury. Before his setback, Tiernan spent the early part of training camp working with the second unit while splitting time between the left and right tackle positions. He experienced difficulties during his first preseason game appearances. Team officials view his return to the field as a key factor in his development. As he continues his rookie campaign, Tiernan is scheduled to work alongside veteran tackle Christian Darrisaw to refine his professional technique.
