BOSTON -- During Sunday's Game 4 of the Eastern Conference finals at the TD Garden, the Celtics put up a video montage during a second-quarter timeout showcasing a handful of New England Patriots in attendance, including coach Bill Belichick, (freshly head-shaven) Rob Gronkowski, Wes Welker, Jerod Mayo, Vince Wilfork and Kevin Faulk.

Gronkowski must have filmed a crowd pump-up video at the game and it aired midway through the fourth quarter (and he got even more video board time in the extra session).

The Celtics won Game 4, 93-91, in overtime, tying the series at two games apiece.
