Georgia Tech coach Paul Johnson did not have an injury update regarding quarterback Lucas Johnson, who suffered an apparent lower-leg injury on Saturday in the team's first scrimmage.

“We won’t know for sure until they do all the testing, but we’ll let you know as soon as we know,” Johnson told media following the team’s Monday practice, the 10th of the preseason.

With Johnson out, James Graham is practicing at both quarterback and wide receiver. Graham, a freshman recruited at quarterback, was moved from quarterback to wide receiver this past Thursday after injuries caused a shortage there. But Johnson’s injury reduced the quarterback depth among scholarship players to starter TaQuon Marshall and redshirt freshman Tobias Oliver, not including Graham.

Oliver had runs of 39 and 56 yards in the scrimmage on Saturday.

“He’s doing O.K.,” Johnson said of Oliver.
