Daniel Theis missed out on the Boston Celtics’ postseason run last year. The German big man was sidelined after tearing his meniscus in March.

He’s working hard to get back to full health, and provided an update on his progress on Wednesday evening. Things appear to be moving forward as planned.

“For now, I haven’t had a bad reaction,” Theis said, per The Boston Sport’s Journal’s Brian Robb. “I have started sprinting and jump shots, and my knee has never reacted badly. There’s no timetable for it, but I think and hope I can do one-on-one stuff this month.”

Theis will find himself competing for minutes in a suddenly crowded frontcourt when he does return. Boston re-signed Aron Baynes and drafted rookie Robert Williams III this summer, and is likely to rely heavily on smaller lineups, in which one of its wings fills in as a big.

That’s a leaves a lot of players trying to get a slice of the playing time pie. Theis deserves the benefit of the doubt ahead of the likes of developmental projects like Guerschon Yabusele or Williams, but he’ll need to re-prove himself if he hopes to claim a substantive role.

Getting healthy is the first step in that process.
