Cheryl Fiandaca of WBZ-TV reported the news Tuesday.
TMZ Sports noted Gronkowski called police after returning home from Minnesota to report the stolen items. The police report said the burglary took place Sunday night around 8:50 p.m. ET, right as the Super Bowl was taking place at U.S. Bank Stadium.
"This isn't an emergency ... this is just uh, Rob Gronkowski calling," he said during the 911 call Monday, per TMZ. "And while I was gone, my whole house got robbed while on the Super Bowl trip and I just got back."
It's unclear what else was taken from the residence, which the Patriots star shares with two roommates.
Gronkowski made nine catches for 116 yards and two touchdowns in Sunday's championship game, but it wasn't enough as the Philadelphia Eagles edged the Pats, 41-33.
