With the Celtics trailing by two points and 2.9 seconds on the clock, Gordon Hayward inbounded the ball to Jayson Tatum, who missed a fadeaway jumper from the right corner to seal Boston's 105-103 loss.

Irving's body language suggested Hayward made the wrong inbound pass, and that what Hayward executed wasn't what the Celtics drew up in the huddle in the preceding timeout.

The result was Boston's second straight loss, as the C's leave Florida without a win after Thursday's defeat in Miami against the Heat.
