Anthony Kim, the former PGA Tour star – whose once promising career was sidelined by injuries, has reportedly been in talks with the PGA Tour and the LIV Golf League about a return to pro golf, sources confirmed to Pro Golf Weekly on Friday morning.

The now 38-year-old Kim, who last teed it up on the PGA Tour in May 2012 at the Wells Fargo Championship, where he withdrew after the opening round and underwent surgery to repair an Achilles tendon a month later.

Sources confirmed to Pro Golf Weekly that Kim has “amped up his training” in recent weeks.

Kim is said to be targeting a potential return in the spring, ahead of the Masters. One potential roadblock is a permanent disability insurance policy, worth $10 million to $20 million. Sources say Kim will be required to refund the entire settlement.

According to Golf.com, Greg Norman, LIV Golf commissioner, wants to sign Kim to a one-year deal to join Jon Rahm’s team , while the PGA Tour “would welcome” his return.

The mysterious Kim, who hasn’t played pro golf in more than a decade, has been the subject of online conspiracies, rumors and sightings for years by golf fans.

The former Oklahoma star turned pro in 2006 and was considered one of the two or three best young golfers in the world, ranking as high as No. 6 in the world in late 2008 at just 23. He would go on to star for the Americans in the 2008 Ryder Cup matches, famously beating Sergio Garcia 5-4 in Sunday’s singles matches. By early 2010, the then 24-year-old had won three PGA Tour titles in less than two years, finished third at the 2010 Masters and was once again a world top-10 ranked player. Injury (and mystery) followed, though, and his one promising career seemed to have come to an abrupt end in the middle of the 2012 season. He was only 26.
