Late in the season, against the Jacksonville Jaguars, Morgan was involved in a controversial ruling when he bobbled a fourth-down pass from Tim Couch; although Couch subsequently spiked the ball on the next play, officials reviewed Morgan's catch afterward and ruled he did not have possession of the ball.

[3] In 2002, he had his best season as a professional, recording 56 receptions for 964 yards, a 17.2-yard average (led the NFL) and 7 touchdowns, while helping the team make the playoffs.
