Recap: Indianapolis vs. San Francisco

By Sports Network

Indianapolis, IN (Sports Network) - Peyton Manning threw for 347 yards, but it was Joseph Addai that threw the game-winning TD pass to Reggie Wayne in the fourth quarter, as the Indianapolis Colts survived a tough test from the San Francisco 49ers and kept their undefeated season intact with an 18-14 victory at Lucas Oil Stadium.

Manning was not at his sharpest despite logging his sixth 300-yard passing game of the season, connecting on 31-of-48 throws and becoming only the fourth player in NFL history to reach 4,000 completions. He was also sacked three times -- something that had happened only two previous times this season and not at all in the last five games.

In addition to throwing his first career touchdown pass, Addai ran for 62 yards on 20 carries, while Wayne shrugged off a groin injury to catch 12 passes for 147 yards and the all-important go-ahead score just seconds into the final quarter. Wayne has caught a touchdown pass in five consecutive games and in six of seven tilts this season.

Matt Stover did most of the damage, hitting all four of his field goal attempts for the Colts (7-0), who extended their franchise-record regular- season win streak to 16 games. It's the longest active streak in the league and tied for fourth longest in NFL history.

Alex Smith, getting the start after replacing an ineffective Shaun Hill in last week's close loss to Houston, completed 19-of-32 passes for 198 yards with one score and an interception.

Vernon Davis, who came into Sunday leading the league in TD receptions, had another during a three-catch, 20-yard day. Frank Gore had a 64-yard TD run and finished with 91 yards on 13 carries.

Michael Crabtree caught six passes for 81 yards for the 49ers (3-4), who lost their third straight and fourth in the last five games.
