You’ve got to give Kristaps Porzingis credit. If what he says is to believed, he’s willing to risk his career to get back on the court in the NBA Finals.

That’s easier said than done, though, as he suffered torn medial retinaculum allowing dislocation of the posterior tibialis tendon. Don’t worry, we had no idea what any of those words meant either, but here’s an explanation from a doctor.

According to the doctor above, it could be a career-ending injury if pushed too far, which the Boston Celtics certainly wouldn’t want. Even though it’s the NBA Finals, Boston do have a lot of depth at the team. Porzingis is still listed as day-to-day, but considering his history of leg injuries, the team may not want to risk creating permanent damage.
