Champion Phil Mickelson and world number one Vijay Singh became embroiled in a spat over spike marks during the weather-hit Masters on Friday.
Singh, 42, complained to officials that Mickelson's golf shoes had caused spike marks on the 12th green.
"There was a complaint from Vijay and one of our referees was called to inspect the spikes and to take off any burrs," said a tournament spokesman.
"Some of the spikes were old ones but Vijay wanted something done about it."
Mickelson was spoken to by an Augusta National official as he walked off the 13th tee.
The two players were later said to have had a heated
discussion in the champions' locker room over the incident.
"After sitting in the locker room for a while, I heard Vijay talking to other players about it and I confronted him," world number four Mickelson said in a statement.
"He expressed his concerns and I expressed my disappointment with the way it was handled. I believe everything is fine now."
Masters rules chairman Will Nicholson later added that no further action was taken.
"No, there wasn't a ruling," he told reporters. "We got a call and how it got labelled on to Phil I have no idea.
"One of our officials talked to Phil to see if there was a burr on the side of one of his spikes.
"He very generously, as you know he would, said he would change them when he got in if there was any problem.
"There wasn't. If there were those spike marks, they were created by a person or persons unknown."
