The 26-year-old, who has represented his country in the Presidents Cup, is currently 11th in the Ryder Cup standings but the latest comments may have damaged his chances of being included in Paul Azinger's side.
Speaking to American magazine "Golf", Mahan said: "From what I've heard the whole week is extremely long.
"You've got dinners every night - not little dinners, but huge, massive dinners. I know, as players, that's the last thing we want to do.
"We want to prepare ourselves. That's part of the whole thing: you're just a slave that week."
He added: "At some point the players might say, 'You know what - we're not doing this anymore, because this is ridiculous'.
"Don't be surprised if it (a refusal to play) happens. It's just not a fun week like it should be."
