Aussie tennis star Nick Kyrgios has withdrawn from his first-round match with American Tommy Paul at the Delray Beach Open in Florida.
Kyrgios, who was set to be the top seed in a tournament for the first time in his professional career, said he's been managing a minor wrist injury but couldn't get up for the game.
"I’m dealing with a little bit of a left wrist injury; been dealing with it for the last week or so," Kyrgios told Tennis.com.
"Some sort of tendon thing. Apart from that feeling pretty good."

That match was due to be Kyrgios' first since his round-of-16 Australian Open exit at the hands of Rafael Nadal.
Jordan Thompson was the next Aussie to face trouble, retiring before the second set of his match with Serbia's Miomir Kecmanović, having dropped the first 6-2.
Kyrgios and Thompson are scheduled to play the Bryan brothers in the first round of the men's doubles though that match now looks a doubt as well.
Meanwhile, Bernard Tomic, who made it into the first round at Delray as a lucky loser, lost to Germany’s Cedrik-Marcel Stebe.
Tomic went down 6-2 3-6 6-2, continuing a difficult start to the season for the former world number 17.

A win over Denis Istomin at New York Open qualifying was his first and only one for the season, then followed a bizarre 6-2 6-0 loss to Ernests Gulbis in Delray qualifying, complete with an apparent tank and some very strange (read: bad) umpiring.
It hasn't been a successful trip to Florida for the Aussies, after fifth-seed John Millman suffered a 3-6 6-4 6-2 defeat to Japan’s Yoshihito Nishioka in the first round of the tournament.
