Cummings replaced Crist late in the game against Oklahoma State two weeks ago and provided enough of a spark to earn the job last week at Oklahoma. The redshirt freshman was 10 of 21 for 111 yards with two interceptions in the 52-7 loss to the Sooners.
Crist played sparingly against at Oklahoma, going 3 of 6 for 13 yards.
Crist was handed the starting job as a fifth-year senior after transferring from Notre Dame midway through last school year. He had been recruited there by Weis, who was eventually fired by the school and hired this season to take over the Jayhawks.
