Roger Federer spotted using crutches during Laver Cup, Casper Ruud says the Swiss' introduction gave him "chills"

Roger Federer was seen leaving the TD Garden in Boston, home of the 2021 Laver Cup, on crutches after Friday's set of matches. Federer was in attendance for the match between Casper Ruud and Reilly Opelka and the Swiss received a standing ovation when his name was announced midway through the first set.

The 40-year-old recently underwent a third surgery on his knee and it was believed that he would follow the proceedings of the Laver Cup from the comfort of his home. However, the Swiss' passion for the event seems to have given him the motivation to travel all the way to Boston.

It is pertinent to note that Federer has been pictured doing numerous promotional activities and interviews for the event, but Friday was the first time the 20-time Major champion was seen walking with the help of crutches.

In the videos, Federer can be seen walking quite gingerly while using the crutches, especially when going down the stairs.

While announcing his decision to have surgery, Federer had mentioned that he would need crutches for some time, but the fact that he was seen with them broke the hearts of millions of fans.

This event, especially he was one of the guys who made it all happen and started it, so he deserved all the crowd cheer he gets."
