Cincinnati Bengals quarterback Joe Burrow is undergoing surgery to have his appendix removed, NFL Network's Ian Rapoport said Tuesday.

Burrow is expected to miss practice time during training camp but make a full recovery before the defending AFC champion Bengals begin their season on September 11 against the visiting Pittsburgh Steelers.

The news comes one day after team owner Mike Brown said Cincinnati's "whole focus" is to get an extension in place with Burrow, who is eligible to negotiate a new deal after this season – his third in the NFL.

"Right now our obvious, most important issue will be our quarterback," Brown said on Monday. "It's not quite ready or ripe yet, but it's right down the track and we see the train coming."

Burrow went 2-7-1 as the starter in 2020 after the Bengals selected him with the No. 1 overall pick in the NFL Draft. He tore his left ACL and MCL in Week 11 that season before returning last year and leading Cincinnati to their first playoff berth since 2015 and first Super Bowl appearance since 1988.

The Bengals led the Los Angeles Rams 20-13 in the third quarter of the Super Bowl before eventually losing 23-20. Burrow passed for 263 yards with a touchdown and no interceptions against the Rams.

"We couldn't be happier with Joe Burrow," Brown said. "He's everything you would wish for, especially for a quarterback in Cincinnati. And our whole focus is going on keeping him here."
