FT: Stormers 32-28 Harlequins
While we wait for the second half, here's a reminder of what we have seen in the Champions Cup already today...

In a blistering start, the hosts' Deon Fourie and Alex Dombrandt of Quins exchanged tries before Steven Kitshoff re-established Stormers' lead.
Fourie doubled his tally before Damian Willemse's finish and a Willie Engelbrecht score added the gloss.
Dombrandt, Andre Esterhuizen and Joe Marchant scored late consolations.

Here's Mantej Mann to guide you through what I hope is another 40 minutes of high octane rugby!
