Stormers flank Rynhardt Elstadt received an off-field yellow card following the match against the Bulls at Loftus.
Elstadt was punished for a 59th minute incident where he grabbed Akona Ndungane by the hair and forcefully pulled for a short period of time.
It is Elstadt’s third yellow card of the campaign and he will now appear before judicial officer. It is likely he will receive a ban, further depleting the injury-hit Stormers.
There was also an off-field yellow for Bulls flank Arno Botha whose tackle on Bryan Habana in the 59th minute was deemed to be dangerous.
