More Celtics bad news: Marcus Smart thumb injury (UPDATE: torn tendon) & Kyrie Irving's knee a cause for concern?

Earlier today, the Boston Celtics announced that Daniel Theis would be out the rest of the season with a torn meniscus. The Celtics, already short-handed due to Jaylen Brown going through concussion protocol, have suffered on the injury front this season and could use a break from bad news.

Unfortunately it keeps coming. Marcus Smart reportedly has a sprain in his right thumb (the same hand he used to punch a picture frame earlier this year).

In addition, Kyrie Irving's knee could keep him sidelined for a few games:

We have seen Terry Rozier step up to shoulder the scoring load in the games where Irving has been absent, as well as contributions from Shane Larkin, but potentially losing both Smart and Kyrie at the same time for several games could be a huge concern for Boston's already depleted line-up.

Stay posted to for future injury updates before Wednesday's game against the Washington Wizards.

Update: Marcus Smart has a torn tendon.
