"As has always been the case, our entire offensive staff will work together in game planning, but there needs to be one coach who calls the plays and Josh will have that responsibility," Stoops said. "Josh has a good feel for the game and the rhythm that we've been able to establish.
"This is a great way to maintain our current style and continuity. Our current style fits our personnel and allows us to remain balanced, something that is important to me."
Heupel, who quarterbacked OU to its 2000 National Championship, is in his sixth season as a full-time member of the coaching staff.
He joined the staff as quarterbacks coach back in 2005 prior to the Holiday Bowl win over Oregon, and he was also a graduate assistant at OU from 2003-05 before serving as the tight ends coach at Arizona for a season.
Norvell came to OU in 2008 and has been the receivers coach as well as assistant offensive coordinator since arriving in Norman.
Wilson will remain with the team through the Fiesta Bowl but only as a position coach with tight ends and fullbacks.
Stoops said he has no timetable for filling the coaching vacancy created by Wilson's departure.
