Northampton face Leinster in Dublin on Saturday, 3 May before holders Toulouse face Bordeaux Begles in an all-French face-off the following day.

Pollock had made only one Premiership appearance before the start of this season, spending much of last campaign on loan at Championship side Bedford.

However, the departure of back rows Courtney Lawes and Lewis Ludlam has accelerated his progress, and, after winning the under-20 World Cup with England last summer, he has become a key part of the first team.

Pollock scored two tries off the bench on his Test debut against Wales at the end of England’s Six Nations campaign and has been touted as a possible bolter for British and Irish Lions squad selection in May.
