Roger Federer injury comeback under threat as star hit with 'mistakes' claim

Roger Federer has been warned of the "dangers" of making a return to the tour later this year following his third knee surgery. The 20-time Major winner has been out of action for almost a year and is set to make his comeback at the Laver Cup before playing the Swiss Indoors Basel, but he has been criticised for "making mistakes" in the past ahead of his return.

Federer has played just five tournaments in the last two years, undergoing double knee surgery in 2020 before returning in Doha last year. But a few months later he was sidelined once again following a new "setback" he suffered during the grass court season and underwent a third surgery.

He is now set to return at the Laver Cup in London's O2 Arena in September before playing his first ATP Tour event at his home tournament in Basel a month later. But former pro-turned-businessman Ion Tiriac has cast doubt over the 40-year-old's comeback and claimed he should not attempt to compete anymore.

"Federer can't be competitive at 40. He can play tennis for fun. Which would be a great thing," he told claytenis. "Though, watch out: it would be a shame if he made a fool of himself. I see it as a danger, because he hasn't played for so long... And he also makes mistakes."
