Ulster must stay 'switched on' against Glasgow, says Henderson

Ulster forward Iain Henderson says the Irish province's players must concentrate for the full 80 minutes in Friday's Pro12 game against Glasgow at Scotstoun.

Ulster have lost their last five away matches against Glasgow, a record they hope to put right this week.

"Glasgow are a really good side who play good rugby for the full 80 minutes. As soon as a team switches off they'll score points and tries," warned the Ireland international.
