The Reds have been hit by a double injury blow ahead of their sixth Round Super Rugby match against the Lions in Johannesburg as two players have been sent home to Queensland.
Wallabies rookie Chris Feauai-Sautia was sent home as he suffered hamstring pain after completing a full training session in Johannesburg.
The Reds have also lost reserve Ben Daley for up to six weeks after scans detected a grade two medial ligament strain.
The Reds bigger concern though is Feauai-Sautia needs longer on the sidelines and he will have scans when he gets back to Brisbane.
Twenty-year-old Feauai-Sautia, who repeatedly suffered hamstring tears and strains as a schoolboy, scored two tries in the Reds 43-33 win over the Cheetahs.
The two cap Wallaby has been enjoying good form suince he won the 13 jersey in round four so the Reds will miss him this weekend againstr the Lions.
"It doesn't look like anything major but given his history we thought it was appropriate," coach Richard Graham told AAP.
"And we've got two Wallabies in Taps (Ben Tapuai) and (Anthony) Fainga'a so we've got a lot of confidence in our squad."
Tapuai looks set to win the 13 jersey with Fainga'a on the replacements bench for the match at Ellis Park this weekend.
