Duane Vermeulen will be sidelined for a fortnight after concussing himself against Toulouse last weekend.

The Toulon No 8 left the field in the 44th minute after a try-saving tackle on Maxime Medard went wrong.

'Just a quick update on my injury from the past weekend top 14 clash: all good got knocked out in the tackle and woke up with a neck spasm,' said Vermeulen on Twitter. 'I will make a full recovery within 2 weeks. Thanks for all the well wishes, I appreciate it a lot. Cheers tweeps. Vrede.'
