Upgraded to available Dieffenbach (undisclosed) has been upgraded to available for Saturday's game against Purdue.

Impact Dieffenbach hasn't played this season, but he's cleared to do so and should compete for the Bruins' QB2 role behind Nico Iamaleava, with Madden Iamaleava as his competition.

Still limited in practice Dieffenbach (undisclosed) continues to be limited in preseason practice, David Woods of On3.com reports.

Impact Even though Dieffenbach recently stepped onto the practice field, his purpose was to get loose on easy items like handoffs and short passes. The quarterback's injury status does not look like it has really improved, so with just over a week before UCLA's regular-season opener, he will remain questionable. Dieffenbach is competing against Madden Iamaleava for second-choice snaps, so if Nico Iamaleava were to go down, the injured signal-caller being QB2 would be crucial going into this season.
