Dallas Cowboys head coach Mike McCarthy is scheduled to undergo surgery on Wednesday to address an acute case of appendicitis, the team announced. 

McCarthy began experiencing abdominal pain this week and eventually visited the Cowboys' medical staff. He is expected to be released from the hospital later on Wednesday. Dallas will host their NFC East rival Philadelphia Eagles on Sunday. McCarthy is expected to coach at that game.

However, McCarthy will miss Wednesday's practice. Assistant coaches Dan Quinn, Brian Schottenheimer and John Fassel will lead the practice while McCarthy recovers from the procedure.

If McCarthy is not available on Sunday, Quinn could put on the head coach's headset for the pivotal matchup with the Eagles. Quinn has previous head coaching experience, serving as the Atlanta Falcons' head coach for more than five seasons.

Quinn also filled in late in the 2021 season when McCarthy had to sit out due to a positive COVID-19 test.
