The Boston Celtics held their 2025 media day at the Auerbach Center on Monday morning.

One of the biggest topics of conversation was Jayson Tatum's progress following the torn Achilles tendon he suffered in the second round of the playoffs last season.

Celtics' president of basketball operations, Brad Stevens, offered some insight as to the rehabilitation process and where Tatum is in his recovery.

"He's been great with his rehab, he's been great with his consistency. He's worked his ass off," Stevens said via NBC Sports Boston's live reporting from the event. "He's been in the market the whole time, and that makes such a difference, right? He's not traveling all over the place. He just put his head down and went to work. I think there were a lot of emotions early on, and then it became a goal, and then it became a mission. That's what he really focused on."

Saturday, Tatum released a workout video which showed him lifting weights and running drills at the Auerbach Center. He is only four months out of having surgery. His display surprised many people. However, it did not surprise Stevens, who has personal knowledge of how hard Tatum is working to try and make it back for some part of this NBA season.

"The video, to me, I understand the way it would look to all of you, but I've watched every step," Stevens said. "He kicked me off my treadmill like three weeks ago. I was just like, 'You know this is mine. You can have all the rest of the stuff in here, but this is the one that I use.'

"But when Jayson Tatum needed to use the treadmill I had to get off and try the elliptical," Stevens continued. "It's like, 'Would you get on the court so I can get my treadmill back?'"

Tatum took to the podium to discuss his injury and he believes he is in a really good position right now.

"I’m in a really good spot," Tatum said. "It’ll be five months tomorrow, so how has it been? It's been a long journey."

Tatum discussed his workout video and said it gave him a jolt in his recovery. He called it a "bright spot" in his long journey back.

"Getting back on the court and being able to participate in a basketball workout was one of the brighter spots in this journey," Tatum said. "It just felt really good to be on the court and dribbling the basketball, going through a workout, feeling like a basketball player again."
