Cincinnati Bengals quarterback Joe Burrow is undergoing surgery to remove his appendix, a source told NFL Network's Ian Rapoport.
Burrow is slated to miss some practice time due to the procedure, Rapoport added.
The star quarterback led the Bengals to their first Super Bowl appearance in 33 years last season. He threw for 34 touchdowns to 14 interceptions while completing 70.4% of his passes for 4,611 yards.
