After his Wimbledon upset of world no. 2 Rafael Nadal, Nick Krygios was primed to be one of the rising stars in tennis. That climb is temporarily stopped as the 19-year-old suffered an arm injury that caused him to miss the 2014 Cincinnati Open.

Kyrgios himself tweeted the development on Tuesday:

Gutted to pull out of @CincyTennis but I've been suffering with bone stress in my left arm. MRI results were positive. Will be okay for USO.

Aside from declaring that he’d be ready for the next and final Grand Slam of the year, Kyrgios also mentioned that the injury did not stop him from practicing.

Kyrgios famous upset of Nadal came in the Round of 16 of the Wimbledon Championship as the Aussie won the five-setter against the Spaniard, 7-6 (5), 5-7, 7-6 (5), 6-3. He fell to Canadian Milos Raonic in the quarterfinals, 7-6(4), 2-6, 4-6, 6-7 (4).

In the recent 2014 Rogers Cup, in Toronto, Canada, he beat Santiago Giraldo of Colombia in the Round of 64, 7-6 (3), 7-5 but got booted out by Andy Murray (Great Britain) in the next round, 6-2, 6-2. The win against Giraldo was important though as it was the Australian’s first ATP World Tour Masters 1000 victory in his career.

After the Aussie's breakthrough victory at the All-England Club, Kyrgios climbed to No. 66 in the ATP men’s singles world rankings. As of August 11, 2014, he is now ranked 58th in the world easily his career-high in the ATP leaderboard.
