Nick Kyrgios and Bernard Tomic at centre of drama at Delray Beach Open

Nick Kyrgios has withdrawn injured and Bernard Tomic has produced another bizarre display on a dramatic day for the Aussies at the Delray Beach Open.

Kyrgios pulled out of the ATP Tour event just hours before his first round match against Tommy Paul on Tuesday (local time).

The top-seeded Australian has withdrawn from the singles tournament, but will still take part in the doubles draw.

Kyrgios' withdrawal means that all four Australians have failed to progress beyond the first round of the ATP 250 tournament in America.

“I'm dealing with a little bit of a left wrist injury; been dealing with it for the last week or so,” Kyrgios said on Monday.

“Some sort of tendon thing. Apart from that feeling pretty good.”

Lucky loser Daniel Elahi Galan Riveros will take the 24-year-old's place in the draw.

Kyrgios will still partner countryman Jordan Thompson, who retired in his singles defeat to Serbia's Miomir Kecmanovic, in the doubles.

Tomic falls in latest bizarre display

Meanwhile Bernard Tomic, who entered the main draw as a lucky loser, lost his opening round match 6-2 3-6 6-2 to Germany's Cedrik-Marcel Stebe.

It was Tomic’s latest bizarre display after causing controversy with a string of lacklustre performances over the past week.

The much-maligned decided to take his shirt off as he walked to the net to shake Stebe’s hand.

Tomic was beaten 6-2 6-0 in just 53 minutes by Ernests Gulbis in the second round of qualifying on Monday.

However he remained in the ATP 250 tournament after being drawn as the lucky loser to replace Tennys Sandgren, who withdrew due to knee pain.

The 27-year-old has plummeted to 191st in the world, having been ranked a career-high 17th just four years ago.

Tomic's quickfire loss to Gulbis, in which he won just three points in the second set, was the second longest of his past five matches.

He endured the second-fastest defeat of his career last week in New York, falling to Japan's Go Soeda 6-2 6-1 in just 39 minutes.

He lost to world No.306 Brandon Nakashima in just 44 minutes in Dallas earlier this month.

Elsewhere, fifth-seeded Aussie John Millman suffered a 3-6 6-4 6-2 defeat to Japan's Yoshihito Nishioka in the first round of the tournament on Tuesday (AEDT).
