What's up for grabs?
Besides the all-important two points in the race for Aviva Premiership play-off place, the match could also have a huge bearing on the British and Irish Lions.
Warren Gatland names his 42-man squad to tour New Zealand three days after the match in Milton Keynes and a number of Lions hopefuls are set to feature.
Northampton Saints' Dylan Hartley will pack-down against his England understudy Jamie George, with the Saracens hooker backed to be selected ahead of his international captain.
Hartley admits he is 'in the dark' over whether he will picked to tour New Zealand.
“I think it is the ultimate privilege for any players from the British Isles,” he said.
“To go would be one hell of an experience I am sure, from what I have heard from previous tours. For the guys that do make the tour it will be the trip of a lifetime.
“I am not counting my chickens and I am not getting my hopes up because in a week’s time it could all be taken away. It is one of those things. It is around the corner, you know it is around the corner. It is not something I am overly thinking about or worrying about. I am just thinking about week to week.
“I have [faced] a good line of hookers [in succession]. I have had Tom Youngs, Tommy Taylor last week. I could have Jamie George this week then Luke Cowan-Dickie the next.
"They just don’t stop coming so I am just enjoying the games. That is uncontrollable, that stuff [the Lions]. I can’t comment on it – I don’t know what is happening. Either way I am going to be in a good place wherever I am this summer.”
What are the betting odds?
Northampton Saints 17/10
