Daly requested the cart due to a deteriorating knee, but while the USGA has allowed carts under certain circumstances - and is apparently doing so for this year's tournament - it did not grant one to Daly. "Don't know what's ahead for me", Daly wrote in a Twitter post.
The two-time major victor asked the USGA, who run the tournament, if he can use a buggy during play but that request was denied.
In his tweet, Daly referenced tha ADA - the Americans with Disabilities Act of 1990 - which "prohibits discrimination based on disability".
It later released a longer statement: "Consistent with the ADA, the USGA reviews each request for cart usage on a case-by-case basis, and can confirm John Daly followed the USGA process, which includes working with a medical consultant".
HoSung Choi sent social media wild this weekend... I fall under the @ADANational but @USGA turned down a cart for me this week. We respect the privacy of all players and can not discuss any medical conditions. We offered Mr. Daly the opportunity to provide additional information to support his request for a cart.
"I'm not going to mislead the media or my fans". He also criticized their handling of Shinnecock Hills during the U.S. Open, saying, "It just seems like something happens every year they host an event that looks bad on them".
"Any claim to the contrary is pure fiction".
The US Senior Open starts on Thursday in the rarefied air of Broadmoor Golf Club at the foot of the Rocky Mountains in Colorado Springs.
"However, his submission did not support a waiver of the walking condition". We offered Mr. Daly the opportunity to provide additional information to support his request for a cart. He played with a cart last week on the PGA Tour Champions and finished inside the top 10 at the American Family Insurance Championship. "He informed us (Monday) morning that he chose to withdraw".
