Peyton Manning breaks NFL all-time passing yard record

Denver Broncos quarterback Peyton Manning has broken the NFL all-time passing yards record against the Kansas City Chiefs.

The record of 71,838 yards, held by Brett Favre since his retirement in 2010, was passed with Manning's second attempt of the game.

The former number one overall pick can also pass Favre's all-time regular season win record, which stands at 186, should he lead his team to victory at Sports Authority Field.

Manning spent 14 seasons with the Indianapolis Colts and won a Super Bowl with the team before he joined the Broncos in 2012.
