Boston Celtics

The Boston Celtics will be without Daniel Theis, who suffered a tear in his right plantar fasciitis in Saturday’s win, indefinitely. But the Celtics, and Theis himself, are not overly concerned with the ‘indefinitely’ tag the injury comes with.

“The indefinite timeline sounds worse than the timeline we’ve been given,” Celtics coach Brad Stevens offered Monday. “I think it’s not going to be season-derailing or anything like that. Hopefully we’ll see how he progresses over the next few weeks. Then the next steps will be determined. But they think it will be pretty quick recovery, which is fortunate.”

Speaking with reporters on Tuesday, the 26-year-old Theis, who scored 17 points and hauled in eight rebounds in 19 minutes before the injury occurred, noted that while he’ll be in a walking boot for the next two weeks, it could have been a lot worse.

“After the game I was worried; Everybody knows their body, and when something is wrong, you know it,” Theis, who felt a pop in his foot on the injury, admitted. “The night [in Detroit] was tough.

“I was really lucky.. It’s not going to be too long.”

The German-born Theis, of course, who came to the Celtics are seemingly doing it all in Europe, missed the final 15 games of the regular season and all of Boston’s 19 playoff games a season ago due to a tear of his meniscus.
