Daniel Theis out indefinitely with slight plantar fascia tear in his right foot

The Boston Celtics announced that center Daniel Theis will be out indefinitely with a slight plantar fascia tear in his right foot.

Theis was back in the Boston lineup to start this season, after his 2017-18 campaign was cut short after 63 games due to a torn meniscus in his left knee.

In five games, all off the Celtics bench, Theis is averaging six points and just over three rebounds in 12.2 minutes per game. His value as a reserve center was on the rise, as he took the place of the injured Aron Baynes over the last three games.

In his first year in the NBA, Theis averaged 5.3 points and 4.3 rebounds as a reserve for Boston. He played 14.9 minutes per contest over 63 game (three starts) for the Celtics as a rookie.

Theis’ contract is due to expire after this season. At that point, Boston could make him a restricted free agent by tendering him a qualifying offer. Theis would be subject to the so-called “Arenas Provision”, under which an opposing team could craft an offer sheet that would be difficult for the Celtics to match.

While Theis is out, Brad Stevens is likely to turn to Guerschon Yabusele and rookie Robert Williams III for minutes off the bench. Williams has flashed some potential when given minutes in recent games. Both he and Yabusele would benefit from some additional playing time.

More updates on Theis’ condition and return to play will be posted on CelticsBlog as available.
