Iain Henderson admits he can’t help but think about his potential selection for the British and Irish Lions squad even in the middle of a massive week for Ulster.

The Ulster captain is expected to be included in Warren Gatland’s 36-man Lions’ squad when it is announced next Thursday ahead of the summer tour to South Africa.
