The Broncos said Monday that defensive coordinator Jack Del Rio will assume interim coaching duties while Fox is sidelined for "at least several weeks." Executive vice president of football operations John Elway said Fox had surgery Monday morning and currently is recovering.
Fox planned to undergo the procedure after the season, but the timeline shifted when the 58-year-old coach was taken to a Charlotte-area hospital Saturday after feeling light-headed during a round of golf.
Coming off a bye week, the Broncos have plenty of time to integrate Del Rio into the lead role. The former Jaguars coach spent nine seasons roaming the sideline in Jacksonville, so it's not a matter of inexperience.
We saw the Houston Texans turn to defensive coordinator Wade Phillips after Gary Kubiak collapsed at halftime of Sunday night's 27-24 loss to the Indianapolis Colts. That sudden switch had a visible effect on Texans players and the game itself.
