Arizona State is one game into its season and already the tackle spot is in a bit of a bind.

Head coach Herm Edwards announced on Monday that starting tackle Joey Ramos is out for the season after suffering an injury in the team’s opener against Northern Arizona. Edwards also said that Penn State transfer Des Holmes is questionable to play this week after missing the team’s opener.

With Holmes out, Ramos drew the start at right tackle in Thursday’s opener.

Late in the first half, Ramos was rolled up on as quarterback Emory Jones was sacked. He stayed down for a beat in obvious pain. As he left the field, he was unable to put any weight on his left leg. When Ramos went down, ASU moved Isaia Glass from left tackle to right tackle, then inserted Emmit Bohle at left tackle.

Edwards also updated the injury status of several other Sun Devils, per CBS 5’s Brad Denny.

The Sun Devils travel to Oklahoma State this weekend to battle the Cowboys (1-0). Arizona State (1-0) won its opener against NAU 40-3. In the win, the ground game looked particularly strong. Xazavian Valladay finished with 119 yards and two touchdowns on 16 carries. As a team, the Sun Devils ran all over Northern Arizona, piling up 267 rushing yards at more than 6 yards per carry.

The 12th-ranked Cowboys won their opener against Central Michigan 58-44. The two play each other on ESPN2 at 4:30 p.m. PT.
