It looks like Houston Texans defensive end J.J. Watt is well on his way to recovery from the serious broken leg he suffered in October.
He shared a video Thursday showing his progress as he ran on a zero-gravity treadmill.
Watt expressed a lot of enthusiasm, ending the jog with two thumbs up.
He wrote, "BIGGGG DAYYY!!!! Progress!!!!! #OneDayAtATime".
Watt, who suffered the season-ending injury to his left leg against the Kansas City Chiefs in Week 5, said earlier this month he is on track to return by training camp.
"It's doing really, really well," Watt was quoted as saying by ESPN.com.
"[I'm] very excited about where it's going. It's getting stronger every single day. They let me do a little bit more and more. I get to run again in a little while."
Watt is not sure if he will be back in time for the Texans' organized team activities that go from mid-April to mid-June, but he also does not want to push his return.
"I'd like to [be involved], but I also know that I'm not going to push it," Watt said.
"If I can, I can. If I can't, I can't. My goal is to come back for training camp and be ready to go."
