CR7's first career red came at Villa Park on the final day of the 2003-04 season.
The Portuguese star opened the scoring against Aston Villa in the fourth minute with a long-range strike, but referee Rob Styles dismissed him in the 85th minute for his second bookable offense (diving and time-wasting, respectively). Darren Fletcher also saw red during United's 2-0 victory.
Ronaldo later had the red expunged from the records when Styles reviewed the incidents and decided he was not guilty of diving for the first yellow.
Therefore, this one doesn't technically count toward his tally.
