DURHAM have won the toss and decided to field at Lord's this morning, but quite when that will be remains to be seen.
Conditions were overcast with light intermittent drizzle keeping the groundstaff fit as they rolled the covers on the square and run-ups up and down with great regularity.
It delayed the toss by 20 minutes and not long after it took place, the covers were being brought back on.
Paul Collingwood returned to Durham's line-up after missing the opening-game defeat to Nottinghamshire with a virus. He took the place of left-hander Mark Stoneman, and is set to bat at three. It was the only change from the first game.
Middlesex featured England internationals Andrew Strauss and Steve Finn for the first time this season, but Eoin Morgan is playing for Kolkota Knight Riders in the Indian Premier League. Neil Dexter plays, but has temporarily handed the captaincy to former Derbyshire skipper Chris Rogers to concentrate on his batting.
Former West Indies Test bowler Corey Collymore made way for Finn, while Strauss takes the place of spinner Olly Rayner.
MIDDLESEX: Strauss, Denly, Robson, Rogers (c), Malan, Dexter, Simpson (wk), Berg, Murtagh, Roland-Jones, Finn.
DURHAM: Di Venuto, Smith, Collingwood, Stokes, Benkenstein, Blackwell, Mustard (c/wk), Borthwick, Thorp, Onions, Claydon.
Umpires: Neil Mallender and David Millns.
