When Rassie Erasmus named Quan Horn as his starting fly-half against the Barbarians, the rugby world did a double take. The Lions fullback has never started a match at No. 10 in his professional career. Yet on Saturday, he’ll wear the Springboks’ iconic No. 13 jersey in a warm-up game ahead of critical Nations Championship Tests against England, Scotland, and Wales.
Nick Mallett, the former Springboks head coach, didn’t mince words when asked about the decision. “I really like the left field decision,” Mallett said on the Talking Boks podcast. But he also called it a “fantastic challenge” for the 24-year-old.
Why Horn? The Logic Behind the Move
The Springboks are dealing with a fly-half crisis of their own making. Sacha Feinberg-Mngomezulu is injured. Handre Pollard is prepping for the United Rugby Championship final with the Bulls. And Manie Libbok is being rested. That left Erasmus scrambling for a solution—and Horn emerged as the surprise pick from left field.
Erasmus noted that Horn’s distribution skills caught the coaching staff’s attention, even though “he doesn’t have a 10 on his back.” Mallett echoed that view, pointing out that Horn has often drifted into playmaking phases during Lions matches this season. “He’s often come in from full-back into fly-half in the sort of second or third phase of the game,” Mallett said. “And controlled their passing game. He’s even been utilised to do the cross-kicks and the little chips over the top as well.”
The result? Horn has effectively been acting as a second fly-half for the Lions throughout their 2025–26 campaign. Mallett called it “a lot of number 10 expertise from him in the Lions template.”
The Barbarians Factor: Not a Pushover
Some might assume a Barbarians match is a glorified exhibition. Mallett pushed back hard. “I don’t think Barbarians tend to just throw it around willy-nilly,” he said. “They try and set up a decent structure and get front-foot ball before they start moving. They don’t want to lose by 50 points.”
That makes Saturday a legitimate test—not a walkover. But Mallett pointed out that Horn will have veteran support around him. Inside center Andre Esterhuizen, scrum-half Grant Williams, and outside center Jesse Kriel are all in the starting lineup. “He’s got a lot of experience there,” Mallett said.

Promising Sharks playmaker Vusi Moyo is named among the replacements as the backup No. 10. But the spotlight is squarely on Horn—a player being asked to pivot his entire skill set at international level.
What’s at Stake
The Springboks haven’t confirmed whether Horn will be a long-term project at fly-half or just a one-off experiment. But Saturday’s performance could reshape South Africa’s depth chart heading into November’s Tests. If Horn succeeds, Erasmus gains a versatile weapon. If he struggles, the experience still sharpens a player who’s been the Lions’ brightest backline star all season.
Either way, Mallett is confident Horn knows his role. “He’ll know exactly what his role is in the side playing on Saturday as the number 10 as opposed to a number 15,” he said.
