Tennis legend Rafael Nadal has undergone foot treatment in Barcelona as he plots a comeback to the ATP Tour in 2022.

This comes after the 20-time Grand Slam champion recently made the right decision to call time on his season due to a persistent foot injury.

Nadal will be on crutches for the next few weeks after going under the knife.

Nadal’s academy posted a picture on Twitter on Saturday, with the Spaniard giving a “thumbs up” that the procedure went well.

It’s known that the Spaniard has struggled with Müller-Weiss Syndrome. The condition had flared up in his French Open semi-final defeat to Novak Djokovic in June and subsequently saw him miss Wimbledon.

Müller-Weiss Syndrome is described as “a rare bone disease characterized by spontaneous adult-onset tarsal navicular osteonecrosis”.

The condition causes progressive fragmentation leading to mid- and hindfoot pain and deformity. Treatment can include the use of rigid insoles with medial arch support and a lateral heel wedge.

Nadal played the Washington ATP 500-level event last month but lost his second match there to South Africa’s Lloyd Harris.

He then pulled out of the Toronto and Cincinnati Masters 1000 events before calling it quits for the remainder of the year.
