Middlesex take on the surprise package of the 2012 CB40 season so far, the Netherlands, at Lord's on Sunday 3 June.
England pair Eoin Morgan and Steven Finn should both be available for Middlesex, who have made a decent start to this season's tournament.
Despite losing their last match to a Phillip Hughes inspired Worcestershire, Angus Fraser's side have two victories from four matches so far. They sit in a congested mid-table in group one, with four sides having gathered four points.
They all trail surprise leaders Netherlands though, who have won four of their first five matches against the counties, which included wins over county champions Lancashire and Essex.
Their only defeat came against Middlesex though, in the Hague. Middlesex comfortably chased Netherlands' target of 213 for just two wickets down with 16 balls remaining.
The match makes up part of the Jubilee Weekend at Lord's, with the Lord's Tavern hosting a special Jubilee barbecue throughout the weekend.
Sunday roasts and Bloody Marys will also be available throughout the day.
