What happened: Oklahoma elevated tight ends coach Jason Witten to interim offensive coordinator. The appointment hands primary play-calling duties to Witten with Kevin Wilson also involved in the offensive structure.

Why it matters: The transition marks a significant midseason adjustment for Oklahoma's coaching staff. Witten brings extensive professional football experience to the sideline as the program shifts its offensive leadership.

What to watch: Witten will oversee the offensive scheme and call plays starting with Oklahoma's next scheduled contest.
