SP Marais, Wilco Louw, Oli Kebble, Ali Vermaak, Rynhardt Elstadt and Kobus van Dyk have been declared fit to return for the Stormers.
The news is a timely boost for the Cape Town outfit ahead of their Super Rugby quarter-final against the Chiefs at Newlands on Saturday.
Prop Louw (knee) and flank Elstadt (wrist) were ruled out of last Saturday's clash with the Bulls at Loftus Versfeld after picking up injuries late last week, but have recovered and will be up for selection against the Chiefs.
Full-back Marais and flank Van Dyk have both been out for two weeks with knee injuries and have returned to full training this week.
Props Kebble (hamstring) and Vermaak (calf) will also both be available for the Stormers for the first time since the June international break.
