The centre-back headed home the opening goal of Sundowns' 2-1 victory, but clashed with opponent Mlungisi Mbunjana on his way down and had to be immediately withdrawn on a stretcher.
Following an assessment from team doctor Carl Tabane, De Reuck was replaced by Brian Onyango barely 15 minutes into the league encounter played at Mbombela Stadium in Nelspruit.
“Yes, Rushine is on his feet and it is very good that he has regained consciousness – the medical team needs to be given a lot of praise, both from Mamelodi Sundowns and TS Galaxy for the prompt response,” Mokwena said after the game.
Peter Shalulile went on to add his name to the score sheet in the second half, before Galaxy pulled one back when Djakaridja Traore converted from the penalty spot seconds before the referee blew for full-time.
“It is good to see that he is walking and he is again conscious. I just saw him in the change-room, so that’s very good. He scored a very important goal for us, which opened the game a bit and we are just grateful that he is in a condition to be able to recognise his surroundings now. We are proud of his contribution towards the win,” the coach added.
Downs, who are clear at the summit by 19 points, next host Sekhukhune United at Loftus Stadium on Saturday.
