Jacob Peterson's strike 10 minutes from time completed a stunning comeback as Sporting Kansas City beat Toronto tonight.
The Canadians looked on course for victory when Jackson put them ahead inside 16 minutes after latching onto a Dominic Oduro through-ball.
In first-half stoppage time, the forward almost doubled the home side's lead as he went close with a header.
However, Sporting got back on terms when Graham Zusi fired a shot through a crowded penalty area that Joe Bendik was unable to keep out.
Kansas City's hopes of victory appeared to be dashed when Matt Besler was sent off for a second bookable offence.
Despite playing with only 10 men, Sporting were able to secure victory when Peterson latched onto Dominic Dwyer's inch-perfect pass to silence the home crowd.
The result helps Kansas move ahead of DC United at the top of the Eastern Conference.
