Watch an emotional Isaiah Thomas get introduced in Boston before Game 1 vs. Bulls

The 22-year-old sister of Boston Celtics star Isaiah Thomas died in a car accident Saturday morning, and Thomas decided to play in Sunday's playoff-opener at home against the Bulls despite dealing with the tragedy.

He was understandably emotional in the moments leading up to tip-off, and received a thunderous ovation as he was introduced to the fans in attendance.
