Marnitz Boshoff kicked a drop goal with two minutes to play as the Lions opened up the Super Rugby season by shocking the Cheetahs 21-20 in Bloemfontein.
It was the boot of Boshoff, who also kicked six penalties, which was responsible for all of the Lions' points as they were outscored by two tries to none.
Raymond Rhule and Cornal Hendricks crossed for the Cheetahs, who controlled play throughout but could not convert their dominance into points.
In contrast to Boshoff, Johan Goosen was off his game and missed two early penalty opportunities before the pair traded successful attempts.
In the 20th minute Rhule collected from Willie Le Roux to cross in the corner and Goosen converted, but a couple more penalties from Boshoff ensured the gap at the interval was only one point.
Le Roux was again involved as Hendricks touched down for the Cheetahs' second try following a good period of pressure after the break, with Goosen converting but Boshoff continued to kcik penalties and keep his side in touch.
Elgar Watts replaced Goosen and kicked a penalty, but when Boshoff replied with five minutes to go it put his side in touching distance.
And it was Boshoff who popped up with the late drop goal which handed the win to the inexperienced visiting side.
