But that was not the only incident of a fan injured in a fall at an NFL stadium in Week 12.
In Baltimore, a 48-year-old man slipped and fell on steps in the upper deck of M&T Bank Stadium, according to the Baltimore Sun. Dan Clark of Ferndale, Md., fell to the bottom of a staircase late in the first half of Sunday's game, reportedly suffering injuries to his head in the fall.
The story said he was in "serious condition" at the University of Maryland Shock Trauma Center and was to undergo brain surgery Sunday night.
According to the story:
"Clark's brother, Jim Clark, went to the bathroom with around 4 minutes to go in the first half. Upon returning, he found his brother lying 'in a pool of blood,' surrounded by stadium staff at the bottom of the staircase in Section 521, where the two had been sitting."
In the incident in Buffalo, both men involved were briefly hospitalized and released.
On the NFL's opening day this year, a fan died from a fall off a pedestrian overpass outside Candlestick Park in San Francisco, and two others were injured when a railing collapsed at the Colts' game against the Raiders in Indianapolis.
