Illingworth has played in four games for the No. 23 Cowboys this season, including two starts when Spencer Sanders was injured.
The 6-foot-5, 220-pound true freshman has completed 41 of 70 passes for 554 yards with four touchdowns and one interception. Illingworth was just 5 of 21 for 71 yards in last Saturday's 41-13 loss at rival Oklahoma.
