Seems like he did. From the old Quins board thread on old matches :
30th January 1993 v London Irish at Sunbury
A week before this friendly at Sunbury against London Irish, we had dispatched Wakefield in the fourth round of the Pilkington Cup by the score of 47-18. They were looking for revenge after we had beaten them in a league encounter at the Stoop back in October by 47-24. This match will be largely forgotten except for the twenty man brawl near the end which resulted in the Irish number 8 (Verling) being sent off for stamping. With most of our big names being rested, Paul Challinor with three penalties and a try from Mike Wedderburn saw us home against two penalties from Michael Corcoran.
Quins: Kent Bray, Mike Wedderburn, Gavin Thompson, Mark Evans, Jeff Alexander (Andy Parton), Paul Challinor, Rob Glenister, Simon Brown, Paul Simmonds, Andy Mullins (c), Troy Coker, David Dix, Mark Russell, Chris Sheasby and Richard Langhorn.
Whether that was just a trial or whatever, no idea, but he definitely turned out for Quins. Hope he enjoyed the twenty man brawl!
