Analysis: Daniel Theis to undergo season-ending surgery on torn meniscus

WALTHAM — Daniel Theis will likely undergo season-ending surgery on a torn meniscus in his left knee. The reserve big man suffered the injury in the closing moments of Sunday's loss to the Indiana Pacers on a possession he was guarding Victor Oladipo. Shams Charania of the Vertical was first to report the meniscus.

The 25-year-old was hobbling in the locker room after the game and was scheduled to undergo tests on Monday to determine the severity of the injury, which identified the torn meniscus.

"When his knee went back yesterday, we actually thought live that he hit knee to knee, but it buckled back," Brad Stevens explained at practice Monday. "We did some tests on the court, felt like he could keep going. I think he played the last two seconds, but when he got buckled back on that deal, I guess he tore a meniscus. He's out for the foreseeable future, most likely out all season. It's too bad. He's had an incredible rookie year in my opinion. He's obviously down and he's weighing surgical options right now and will go from there."

The injury brings a premature end to a productive rookie season for Theis in Boston. The 6-foot-9 forward/center averaged 5.3 points and 4.3 rebounds in just 14.9 minutes per game this year. He was an essential mobile defender in Brad Stevens' bench rotation and saw crunch time minutes periodically at center to combat speedy frontcourts in certain matchups.

Theis is under contract with Boston through the 2018-19 season and should be fully recovered from the injury for training camp.
