Waratahs utility back Jono Lance is flying to Bloemfontein to join the Sydney-based side for Saturday's clash with the Cheetahs.
Lance, who has only made two appearances for the defending champions in 2015, is joining the Waratahs after left wing Rob Horne received a three-week ban for a tip-tackle on Lions centre Lionel Mapoe during Saturday's clash in Johannesburg.
"It definitely had crossed my mind that I might have played my last game," Lance told Rugby Heaven.
"There's no guarantee that I'll go over and play but everyone who hasn't been playing has been training as hard as they can to be ready for that opportunity.
"We've been lucky with injuries this year, but a few judicial things have happened in the last couple of weeks, which has allowed an opportunity for some other guys, so we have to be ready, and I'm pretty glad to be flying over."
Waratahs scrum-half Nick Phipps said although Horne's absence was a setback, there was plenty of depth in the squad.
"Rob is one of those players who, in a team of superstars, doesn't get heralded for all he does," said Phipps.
"He's a defensive maniac and makes the impossible possible out on the field, but this will give him a mini pre-season and he'll be back to help us at the back end of the season.
"Jono hasn't been playing much footy with us but he trains the house down every session and if there's an opportunity to jump in you know he's safe as houses, a great defender, and he won't be dropping his head when things get tough."
Lance is expected to fight for a place on the replacements bench with Peter Betham asWaratahs coach Michael Cheika is set to move Adam Ashley-Cooper from outside centre to wing with Matt Carraro coming in to the run-on side to wear the number 13 jersey.
