Celtics superstar Jayson Tatum opened up on his Achilles injury for the first time and used one word to describe the frustrating process of rehab.

But this week, in a social media post ( via Celtics Blog's Noa Dalzell), Tatum opened up about his injury, how he has been dealing with it, and what comes next for the Duke alum. "Rehab is tedious, man — six days a week. It’s starting to get a little bit better now, I’m out the boot now," said Tatum.
