The Dallas Cowboys might be without their head coach for their huge matchup with the Eagles this weekend ... 'cause the team says Mike McCarthy is slated to undergo surgery later Wednesday that could keep him from the sidelines on Sunday.
The Cowboys revealed McCarthy will have a procedure on his appendix after he was diagnosed with acute appendicitis following some abdominal pain he was suffering from earlier Wednesday morning.
The team says the 60-year-old is scheduled to be released from the hospital before sunrise Thursday .
