Paul Azinger says Brooks Koepka should relinquish his place on the United States Ryder Cup team if he does not want to play at Whistling Straits.
Four-time major winner Koepka raised eyebrows when stating in an interview with Golf Digest that he finds the prestigious event "a bit odd" and "hectic".
The former world number one revealed he finds playing in a team event difficult to adapt to, as he is unable to get into a usual routine that he would have during a major tournament.
Azinger, who captained the USA to victory over Europe in 2008, says Koepka ought to give someone else the chance to play in Wisconsin if he is not fully committed.
"I'm not sure he loves the Ryder Cup that much," Azinger said during a conference call for NBC Sports.
"If he doesn't love it, he should relinquish his spot and get people there who do love the Ryder Cup."

Azinger added of Koepka, who has been troubled by a wrist injury: "Not everybody embraces it.
"But if you don't love and you're not sold out, then I think Brooks - especially being hurt - should consider whether or not he really wants to be there."
Azinger continued: "Brooks is one of the most candid, most honest guys there is, and if he's blatantly honest with himself and doesn't want to be there, he should come out and say it."
The United States start their bid to regain the Ryder Cup a week on Friday.
