Stormers centre Damian de Allende has been ruled out of action for 12 weeks with an ankle injury.
De Allende sustained the syndesmosis injury in the second half of the Stormers' 37-24 victory against the Bulls at Newlands on Saturday.
The midfielder joins the likes of Scarra Ntubeni (achilles), Leolin Zas (leg) and Juan de Jongh (knee) on the Stormers' injury list.
'Injuries are part of the game, but Huw Jones will join us for the next match against the Jaguares before heading back to Scotland for the Six Nations,' coach Robbie Fleck commented.
'With Damian out, Jones and EW Viljoen will now play a big role for us during this campaign.'
