Another damaging blow: Nick Kyrgios withdraws from Halle Open singles and doubles with Wimbledon return also under threat

Nick Kyrgios seemingly cannot catch a break. The Aussie has again been dealt with another injury blow and has been forced to pull out of the Halle Open singles and doubles tournaments this week.

The former Wimbledon finalist made a return to the court as the grass season began, getting wildcards for a number of the ATP tournaments. Residing in Germany, he kicked off his return with a win at the Stuttgart Open against the also flashy and flamboyant Corentin Moutet.

It was an emotional return to winning ways with all the hardship he has been through these past few years. He would bow out against Sho Shimabukuro ahead of his doubles campaign starting alongside Alexander Bublik.

The pair of entertainers put on a show against Jakub Paul and Ryan Seggerman, coming out as winners in a third set tiebreak. Unfortunately, that was the most recent time Kyrgios has stepped onto the court, being forced to withdraw from the quarter-finals with a physical issue.

This withdrawal would be quite significant. He has been forced to also pull out of the Halle Open a right knee injury seemingly a troublesome one. Kyrgios was set to face off against the number three seed Ben Shelton in a blockbuster clash. Instead, Shelton will take on Lorenzo Sonego who steps in his place.

The injury issues just continue to keep piling up for Kyrgios. After long term troubles with his knee and wrist, he has never been the same player, lacking match sharpness and fitness while never fully recovering from his problems.

This problem could be hugely significant. The wildcards have been released for Wimbledon, and his name is on there alongside Alexander Bublik in the men's doubles. The prospect of missing the chance to return to SW19 to compete would be a devastating blow for Kyrgios.

Whether this is a precaution to make sure he is 100% fit for the Grand Slam or if it is a serious recurring problem, it is not yet clear. He will do everything he can to get back out onto the court and competing at the highest level.
