Johann van Graan at a loss to explain Munster indiscipline

Head coach van Graan had enough on his plate with the string of injuries sustained during his side’s second-half capitulation to Ulster in Belfast on Monday night, when Munster surrendered a 17-0 interval lead to lose 24-17 at Ravenhill, without the additional loss of centre Sam Arnold to a red card.
Arnold’s dismissal for a dangerous, high hit on Ulster fly-half Christian Lealiifano came with Munster already down to 14 men following a sin-binning for replacement lock Fineen Wycherley as the northern province staged a rousing fightback early in the second half.
