Jon Jones is back on the comeback trail and has an eye on resuming his career.

The heavyweight champion has been sidelined with a torn pectoral muscle that required surgery in October.

Jones worked out for the first time since his recovery period and was encouraged.

"First day back in the gym since my injury, felt amazing. And so it began," Jones said on his Instagram account on Tuesday night.

When Jones was hurt, he was scheduled to defend his title against Stipe Miocic. He withdrew from that bout as part of UFC 295.

Jones, 36, might be able to return this summer or early fall.

Jones is 27-1 plus one no-contest in 29 bouts.
