With backups set to play the majority of snaps on Friday, Kubiak was asked if rookie tight end James Casey will be "unleashed" this week.
"Yeah, we're going to unleash him everywhere this week," Kubiak said with a grin. "Fullback, tight end – he's going to play everywhere. He will play a few snaps this week."
Casey will see considerable reps at fullback because starter Vonta Leach, who suffered a lower leg bruise against Minnesota and didn't practice Wednesday, is not expected to play. The rookie from Rice has been taking reps at fullback since training camp started and said he feels comfortable at the position.
