Provincial Barbarians v British and Irish Lions (08:35 BST)
The pre-match focus has been on Bryn Gatland - son of Lions coach Warren - who starts at 10 for the Provincial Barbarians.
The 22-year-old Blues playmaker has been told by his old man to expect plenty of heavy traffic heading up his channel today.
"I spoke to Bryn last night and he's enjoying the week," said Warren on Friday.
"He'll expect to have to make a few tackles on the weekend."
Gatland senior was part of the Waikato side who beat the Lions on the 1993 tour.
"I have joked with him that we both would have played against the Lions and it's unfortunate that only one of us would have won. I desperately hope that that is the case!"
