Anthony Kim, who blazed a red-hot trail on the PGA Tour for four seasons and then disappeared from public view after injuries derailed his career nearly a dozen years ago, has been in discussions with the PGA Tour and the LIV Golf League about returning to professional golf, sources confirmed to ESPN on Thursday.

Kim, 38, made his last start on the PGA Tour when he withdrew after the first round of the Wells Fargo Championship in May 2012. He underwent surgery to repair an Achilles tendon injury in his left leg the next month. He hasn’t played in a professional tournament since.

Golf.com first reported Thursday that Kim is mulling the possibility of a comeback. Sources confirmed to ESPN that Kim has been ramping up his training in recent weeks.

Kim could play in non-signature events as a past champion or through exemptions on the PGA Tour.

Golf.com reported that the LIV Golf League wasn’t initially interested in signing Kim to a contract but that commissioner Greg Norman called him to begin negotiations on a potential one-year deal.

Even though Kim hasn’t played in more than a decade, he has still been the subject of great interest by golf fans. The former Oklahoma star turned pro in 2006 and tied for second while playing on a sponsor’s exemption at the Valero Texas Open in his first start.
