It's clear that Marcus Smart is one of the most important members of the Boston Celtics. His athleticism, defense, and knack for drawing fouls are all indispensable qualities that have contributed to the Celtics' success this year. As the Celtics begin to head into the postseason this year, they will need their entire team to be healthy for the long road ahead, especially if the franchise wants to win their 18th NBA championship.

After Celtics guard Kyrie Irving injured his knee against the Houston Rockets, many people started to believe that injuries would shape the Celtics' season. However, there is one injury that could hinder the Celtics' success moving forward. Specifically, that's Smart's thumb injury, which could force him to miss the rest of the regular season, per Chris Forsberg of ESPN.

“He's gotta figure out what his next steps are,” Stevens told the “Zolak & Bertrand” show. “He told me today that he's going to take a couple of days, see what it feels like early next week, get all of the different doctors' opinions [then] sit down early next week and weigh his options.

“There could be a slight chance that he's back sooner rather than later, but I'd say that it's not going to be any time too soon. And there's a chance that he would not be back.”

Smart originally injured his hand after smashing a photo on the wall. The Celtics could be in a precarious situation if Smart does not return soon. Smart is the Celtics' defensive anchor, and it would be a shame if he doesn't return when the Celtics will need him most in the postseason. Hopefully, Smart can make a full recovery and return to help the Celtics achieve their championship aspirations this year.
