Football games — and fans — will not be stopped by freezing temperatures and blowing snow. Field grass was camouflaged by falling snow on the East Coast Sunday, transforming four NFL stadiums into a winter wonderland.
Games between the Detroit Lions at the Philadelphia Eagles, Minnesota Vikings at the Baltimore Ravens, Kansas City Chiefs at the Washington D.C. Redskins, and Miami Dolphins at Pittsburgh Steelers were subject to heavy snow, interfering with players’ runs, passes, and catches, fans’ vision and television broadcasts of the games.
In some stadiums, officials used small tractors with plows and hand-held snow blowers to try to clear the field, while bundled-up fans found it difficult to follow the concealed yard markers. FOX used new technology to superimpose the field markings for both the Lions-Eagles and Vikings Ravens games, NBC reports.
