outruck

From out and ruck (etymology 1).

outruck (third-person singular simple present outrucks, present participle outrucking, simple past and past participle outrucked)

1. (Rugby) to outplay an opponent in a ruck

   So potent, indeed, was this offensive amalgam that it almost obliterated further questions. Anything that was not it had attractions: the Welsh rugby team, outrucking Chamberlain and Hoare and Halifax and the young toffs they'd persuaded to stand in for them - Raymond Williams, Wales and England, 1983.
