Marvin Harrison, the Pro Football Hall of Famer and former Indianapolis Colts star, had a disappointing debut with the Arizona Cardinals on Sunday. Harrison, who signed with the team last week, caught just one pass for 11 yards in the Cardinals’ 31-10 loss to the Los Angeles Rams. The 43-year-old wide receiver, who last played in the NFL in 2008, was expected to provide a boost to the Cardinals’ struggling offense. Instead, he was largely invisible during the game.
