6:51pm - Play is abandoned for the day at Emirates Old Trafford, and what a day it has been. Division Two leaders Northamptonshire were skittled for 62 as Kyle Hogg ran riot with 7-27, but the visitors fought back to leave second-placed Lancashire 121 for eight at stumps.

Chesney Hughes is superbly run out for 30 by Richie Berrington from point shortly before rain forces the players off with Derbyshire 36 for two in the 10th over of the game.
5:07pm - Play resumes at New Road. At Derby, Scotland’s Neil Carter ousts Wes Durston for four.
5pm - Northants strike twice in two overs. Agathangelou falls for 21, pushing forward to an Andrew Hall ball that nipped back and hit leg stump, before Muhammad Azhar Ullah has Katich caught behind for 30 via a great catch from David Murphy. Lancashire are 85 for five.

Lancashire, meanwhile, have lost a wicket in just the second over as they respond to Northants' paltry total, Muhammad Azhar Ullah bowling Luke Procter.
2:31pm - What a performance from Lancashire. Crazily, Northamptonshire have managed 42 more than Essex did versus the Red Rose last week. Despite that, they will be far from happy with 62 all out, the catalyst for which was Kyle Hogg's 7-27.
@LancsCCC on Twitter: WICKET!! White, playing to leg, gets a big edge to Prince at 3rd slip off Chapple. Northants 57-9
