Novak Djokovic left followers puzzled as he was seen with a spherical steel piece taped to his chest throughout his match on the French Open. The world No 3 uncovered the piece as he modified his t-shirt throughout his match in opposition to Marton Fucsovics, and he later changed it. It led Jim Courier to joke that he could possibly be Iron Man as viewers took to Twitter to query what it was.

Djokovic discovered himself in a tussle with Fucsovics after taking an early-break lead. The two-time French Open champion was damaged when he served for the primary set and struggled with the wind earlier than taking it in a tiebreak. 

After needing an hour and 27 minutes to take a 7-6(2) lead, the Serb swapped his shirt in the course of the changeover. And cameras zoomed in on a coin-shaped piece that was taped down on his chest.

"Something taped to Novak," former professional Courier stated whereas commentating on the match for Tennis Channel. "Have you ever seen Robert Downey Jr. in the same room as Djokovic? Maybe Novak is Iron Man," he joked.

There was extra confusion when the 36-year-old obtained one other of the steel items from a ball woman, who presumably handed it to Djokovic from his staff. The world No 3 eliminated the primary one from his chest and connected the brand new one.

"His trainer did give the ball girl another one of these," Jason Goodall stated. The commentator observed that Djokovic initially struggled to get to his chest, including: "Novak a little confused as to whether to go over the top or under the bottom. He did change it in the end."
