Oct. 31 (Bloomberg) -- This weekend's game between the New England Patriots and Indianapolis Colts marks the first time two undefeated teams have played this late in a National Football League season, the league confirmed.

Two teams with records of 7-0 or better never have played in the league's 88 seasons, the NFL said in a news release.

The 8-0 Patriots are favored to beat the 7-0 Colts in Indianapolis on Nov. 4 by six points, according to Las Vegas sports books. The Patriots have won three Super Bowl titles since 2001. They are scoring a league-leading 41.4 points a game and have outscored opponents by an average of 25 1/2 points.

The Colts won last season's Super Bowl and have won 11 straight games dating back to last season. Indianapolis has beaten New England in three straight games.
