Jhon Duran has been responsible for some great moments for Aston Villa this season.
He has scored 12 times this season in all competitions, often coming on as an impact sub, none more memorably than when he scored the only goal as Villa beat Bayern Munich in the Champions League.
But Duran's 32nd-minute straight red card for violent conduct ended Villa's chances of getting something from an already difficult task away at Newcastle.
Villa were already 1-0 down, after Anthony Gordon's superb curled strike inside the opening 80 seconds, when Duran was dismissed.
Referee Anthony Taylor ruled the Colombia striker had deliberately stamped on Schar's back after the Newcastle defender had slid in for a challenge, although 21-year-old Duran, who later kicked a water bottle in frustration, claimed the contact had been accidental.
