Arnold had carried will in the first half of a frantic game, and made one nice turnover, but was guilty of a couple of missed tackles. He rushed out of the line and missed the hit to leave Munster vulnerable. George Horne made them pay with his second try of the game, seconds later.
Arnold got back in the line and, as Glasgow piled forward again, attempted to stop replacement back Stafford McDowall in his tracks.
His technique was off - dipping in head first - and he was given a fearful shunt by McDowall, who ploughed on before being brought down by John Ryan.

Arnold was looked at by Munster medics on the pitch and referee Dan Jones was told he had suffered a "stinger" injury (numbness) to the shoulder. As the impact looked serious, he was removed for a HIA and replaced by Alex Wootton.
As the second half got underway, it was confirmed Arnold would play no further part in the match. He will have to follow all the RTP protocols over the coming days and it leaves Ireland with a dilemma.
Arnold could well fly out to Chicago with the rest of the squad, on Monday, but he would not be permitted to take any contact until he has satisfied medics that there are no lingering symptoms from that heavy blow. It would mean he would have to sit out the crucial training runs early in the week.
His Ireland debut may yet be delayed but there are three further chances to line out in green during the Guinness Series, back in Dublin, next month.
