Tennis: Tomic and Kyrgios feud played down

Former Australian Davis Cup captain Wally Masur has played down the public feud between Bernard Tomic and Nick Kyrgios.

Masur said the pair were close friends and Tomic's criticism of Kyrgios' unavailability for the weekend's loss to the United States in Melbourne would not create lingering issues.

"What's happened has happened, and for me the best thing is that they both play Indian Wells in five days time," Masur told Fox Sports News.

"That they just meet up in the locker room ... shake hands and just get on with it.

"We don't play another Davis Cup tie until September so there will be a lot of water under the bridge from now until then."

Tomic, who was battling with a wrist injury, accused Kyrgios of "faking" an illness in Sunday's four-set loss to world No.11 Jack Isner during a courtside chat with coach Lleyton Hewitt.

Kyrgios later fired back on Twitter, telling Tomic he would not have his back anytime soon.

However Masur defended Kyrgios' absence from the tie after he was ruled out by medical staff on Thursday.

"I didn't see him but the word was that he had a virus and his actual mouth was ulcerated and the guy was pretty fatigued," he said.

Masur's claims were backed up by Kyrgios' Davis Cup teammate John Peers, who said he was "a little" disappointed by Tomic's mid-match comments.

"But I think Bernie just got a little heated in the moment but it all calmed itself down," he said.

"I think Lleyton made the right decision to begin with. Nick came down to do a fitness test and according to medical staff didn't get through it.

"So Lleyton had to make the tough decision and go with the strongest team we could put out on the field that was healthy to play."
