27 Daniel Theis PF

Theis (knee) will have his contract for the 2018-19 season guaranteed by the Celtics, Gary Washburn of the Boston Globe reports.

Despite going down with a season-ending knee injury in March of last season, Theis was still a key bench piece in the frontcourt as a rookie when healthy. The 6-foot-9 big man played in 63 games and averaged 5.3 points and 4.3 rebounds across 14.8 minutes. That certainly didn't make him a viable fantasy asset by any means, but he was still a valuable bench piece when looking at him simply for basketball purposes. As a result, Theis will have his $1.38 million contract for the 2018-19 season guaranteed. After being cleared for Alter-G work last month, Theis could make a full recovery prior to training camp.

Theis (knee) began running on the Alter-G on Monday using 70 percent of his weight, Jay King of The Athletic Boston reports. He's expected to be able to run on the court within the next two or three weeks.

Theis, who suffered a left knee sprain in March and needed surgery to repair his MCL, continues to make progress in his rehabilitation. The expectation remains that he will be 100 percent healthy in advance of the 2018-19 campaign.

Theis (knee) said Friday that he's about two weeks from progressing to running, Adam Himmelsbach of the Boston Globe reports.

While Theis has been ruled out for the remainder of the season, it's nonetheless encouraging that the big man is making tangible progress. Theis, who's been traveling with the team throughout the postseason, suffered a left knee sprain in March and underwent surgery to repair his MCL. The expectation is that he'll be back to 100 percent well in advance of the 2018-19 season.

Theis was seen getting shots up following Friday's practice, Chris Forsberg of ESPN.com reports.

Theis, who underwent surgery in mid-March to repair his MCL, shed his crutches in late April, so he seems to be progressing well. It's expected he'll be fully recovered by the time training camp rolls around.

Theis (knee) is walking without the assistance of crutches, per his Twitter account.

Theis underwent surgery to repair his left knee lateral meniscus in mid-March, and is seemingly progressing well in his recovery. He is expected to make a full recovery ahead of training camp.
