FAYETTEVILLE -- Dalton Wagner went from being the Arkansas Razorbacks' second-team right tackle to their starting left tackle before the start of fall camp.
"It's a next guy up mentality," offensive coordinator Joe Craddock said. "That's what football is all about. You never know when something can happen.
"The No. 2 guy you always say is one play away from playing."
Wagner, a 6-9 redshirt freshman from Spring Grove, Ill., became the next man up because junior Colton Jackson is recovering from back surgery that is expected to sideline him for the first six games.
The coaching staff decided in July after learning the severity of Jackson's injury that the best option was to switch Wagner from the right side, where he had been the backup to senior Brian Wallace.
