The 49ers opened the regular season against the Arizona Cardinals on September 10. Despite losing 34-27, many positives can be taken out of the game. RB Frank Gore rushed for 88 yards and caught 6 receptions for over 80 yards with two touchdowns. Rookie tight end Vernon Davis and second year quarterback Alex Smith hooked up for a touchdown pass with Smith equaling his touchdown total of the entire 2005 season and passing for an encouraging 288 yards with 23 completions out of 40 attempts. The 49ers had several chances to win it, however, many controversial non-calls were made by the officials, including a blatant pass interference in the end zone, which would have tied the game with just a little over 2 minutes to go. The 49ers would start their 61st season 0-1.
