Team spokesman Reggie Roberts said a news conference was scheduled later today to introduce Horn, the former four-time Pro Bowl player with New Orleans.

The 35-year-old Horn missed nine games the last two seasons with groin and hamstring injuries, including six games last season. Negotiations with the Falcons gained momentum after Horn passed a physical exam administered by the team.

Horn told the New Orleans Times-Picayune the Falcons are offering him $19 million over four years, including a guaranteed $7.5 million in the first two years.

The Falcons led the NFL in rushing for the third straight year but finished last with only 148 yards passing per game. Petrino plans to add more three- and four-receiver sets to the offense led by Michael Vick. The Falcons lost free-agent receiver Ashley Lelie, a former University of Hawaii standout, to San Francisco.

Horn will join the team as a starter but also will be called on to serve as a position leader for Michael Jenkins and Roddy White, first-round picks who have struggled with inconsistency.

Tight end Alge Crumpler led the team with 56 receptions last season. Among receivers, Jenkins was the leader with 39 catches for 436 yards and seven touchdowns.

Despite missing six games, Horn had 37 catches for 679 yards and four touchdowns last season.
