Glasgow Warriors’ swords sharpened ahead of Ulster semi-final

Glasgow Warriors “know what not to do” as they prepare for Friday’s PRO14 semi-final visit of Ulster, says assistant coach Jonathan Humphreys. Warriors were well beaten by Scarlets at this stage last year after a three-week break from competitive action.

Glasgow’s last match came on April 27 but Humphreys says lessons have been learned from last term’s failings.
