Purdue coach Darrell Hazell chose freshman Danny Etling as the starting quarterback Wednesday and moved former starter Rob Henry to safety.
Hazell also suspended two receivers following their arrests earlier this week. Starter B.J. Knauf will miss the next two games, lose ticket privileges for those games and must fulfill a community service requirement. Little-used backup Jordan Woods has been suspended indefinitely.
The moves came on a busy afternoon during Purdue's bye week.
Etling was expected to be named the starter after Henry was yanked late in the first half of Saturday's 55-24 loss to Northern Illinois after throwing two interceptions on potential scoring drives. Henry, one of the team's most respected leaders, will now try to help fortify a secondary that has been hit hard by injuries this season.
