Ellis will be partnered at half-back by Ronan O’Gara, who will captain the Lions for their last provincial match of the tour to South Africa.
Head coach Ian McGeechan said: “The players are well aware of the importance of the match tomorrow against the Emerging Springboks. We need to step up our performance against a talented outfit whose players, like ours, will be determined to show that they are worthy of a Test place. It should be a great match.”
The game will be screened live in the ABC Bar at Welford Road.
