Football fans with wide berths will get no sympathy at Mile High Stadium, home of the Denver Broncos.
Individual theater-type seats are being installed in place of old benches at the stadium, and they are proving too narrow for some fans' comfort.
Mike Flaherty, deputy director of parks and recreation, said he was approached by Mayor Federico Pena because of complaints about the seats.
But the complainers will just have to adjust, Flaherty said, because the city is spending $4.2 million to put new seats in most sections of the stadium.
"The issue," he said, "is people in the past have been sitting on more seat than they paid for."
"Unfortunately, we're talking about people who are overweight," he added.
