Some possible good news

CSNNE
However, the fact that the 32-year-old Pierce is having additional tests beyond X-rays means in all likelihood, there are no broken bones.

X-rays generally determine whether bones are broken or have some type of fracture.

Magnetic Resonance Imaging tests, better known as MRIs, give a better indication as to whether there's ligament or soft tissue damage.

Either way, there's a good chance that Pierce will miss some games.
Missing some games is fine. Out for the year is not. Ainge is going to let us know tomorrow. Let's hope Paul can come back 100% by the playoffs.
