On October 15, 2006, he kicked a 54-yard game-winning field goal while time ran out against the St. Louis Rams to win the game 30-28. Although it would have been a 49-yard kick, Seattle was called for an illegal formation penalty. Unlike a false start penalty there was no 10-second run-off so Brown still had a chance to kick, albeit from 54-yards out. On November 27, 2006, he tied his career best by kicking four field goals in a snowy "Monday Night Football" game against the Green Bay Packers, with all four field goals made in the first half. On December 3, 2006, Brown kicked a 51-yard field goal to win the game against the Denver Broncos, making it his fourth game winning kick in the last minute in the 2006 season.
