A container holding some of their team's shoulder pads, helmets and footballs was sent to Newark, N.J., by accident, but it safely arrived in Foxborough, Mass., after the team rushed it back to Boston for arguably its biggest game of the season, league sources told ESPN's Adam Schefter.
The outlet reported that the Chiefs were responsible for the mishap after the team never took the equipment -- which included about 35 of the players' bags -- off a plane.
At 2:39 p.m., CBS Sports sideline reporter Tracy Wolfson posted a picture on Twitter of workers carrying Chiefs equipment bags through Gillette Stadium.
"Crisis Averted! Chiefs equipment bags have arrived," she wrote.
If the Chiefs had failed to locate or retrieve the equipment before the 4:25 p.m. kickoff, they would have needed to forfeit, sources told ESPN.
A Chiefs spokesman confirmed to ESPN that the equipment did, in fact, arrive on time.
"I never heard that before," a source told the outlet.
