Title:
Super_Bowl_50

Context:
After each team punted, Panthers quarterback Cam Newton appeared to complete a 24-yard pass Jerricho Cotchery, but the call was ruled an incompletion and upheld after a replay challenge. CBS analyst and retired referee Mike Carey stated he disagreed with the call and felt the review clearly showed the pass was complete. A few plays later, on 3rd-and-10 from the 15-yard line, linebacker Von Miller knocked the ball out of Newton's hands while sacking him, and Malik Jackson recovered it in the end zone for a Broncos touchdown, giving the team a 10–0 lead. This was the first fumble return touchdown in a Super Bowl since Super Bowl XXVIII at the end of the 1993 season.

Question:
Which former referee served as an analyst for CBS?

Mike Carey
