FOXBOROUGH, Mass. — As reporters worked on stories in the press box at Gillette Stadium following the Patriots’ 31-28 victory over the Colts, an unexpected occurrence unfolded on the playing field.

Patriots coach Bill Belichick celebrated the win by playing lacrosse.

Belichick, in a sweatshirt and jeans, was playing catch with Paul Rabil, a former lacrosse star at Johns Hopkins. At one point, Belichick climbed into the stands to retreive an errant ball. At another point, Belichick was receiving passes of almost 100 yards.

All in a day’s work.

Rabil, who plays for the Boston Cannons of Major League Lacrosse in addition to playing for the Stealth in the NLL, tweeted this earlier tonight: “Coach B is dialed in. Keeps his stick in the office. His ‘stress reliever’ is my game.”

Belichick, a five-time Super Bowl winner and head coach of the Patriots since 2000, lettered in lacrosse while attending college at Wesleyan University in Middletown, Conn. As a senior, he was named captain of his lacrosse team. He was inducted into the Wesleyan University Athletics Hall of Fame as part of its inaugural class in 2008, according to his bio on the Patriots website.
