Shane Warne could miss the rest of the English season after fracturing a rib while bowling in Hampshire's draw with Lancashire at Old Trafford . He will be out for at least three weeks, a major blow for Hampshire, who are seeking their first Championship title since 1973. The game had draw all over it from the start, but Paul Horton pushed on to a career-best 152 and Luke Sutton hit his second century of the season to guide Lancashire to full batting points.
Rob Key and Martin van Jaarsveld made centuries as Kent and Worcestershire shared the points in an inevitable draw at Canterbury. There was no change for the bottom three, though, as Surrey didn't manage to fit in a ball against Sussex who watched Yorkshire slide past them to the top. They have a game in hand, though.

Derbyshire held their nerve to bowl out Glamorgan at Cardiff just when the home side were looking good for their second win of the season. Heading into the final session, Glamorgan needed 60 with six wickets in hand, but added just 18 of those before being blown away by Ant Botha's five-for and three wickets for Tom Lungley.
Nottinghamshire will hope that their last six pairings can triumph where Glamorgan failed, in easing the last 104 runs they require to beat Northamptonshire at Trent Bridge. A team effort took Northants to 229 in their second innings, leaving Nottinghamshire to chase 232. The visitors were boosted by removing Stephen Fleming for 50 shortly before stumps.
Jerome Taylor blew through Essex's defences with five wickets, and he was well supported by David Masters (4 for 40) as the home side crumbled to Leicestershire at Colchester. Varun Chopra was caught at slip off the first ball of the day off Masters, who will be an Essex player next season, and resilient fifties for Ryan ten Doeschate and James Middlebrook were the only consolation for them. Leicestershire then reached 52 for 2 and a final-day run-chase may be negotiated between the two captains.
A draw is likely at Lord's where Middlesex reached 305 for 7 before declaring, although a late Gloucestershire collapse to 97 for 5 keeps the game interesting. Andrew Strauss made 75 and Ed Smith 69 before Middlesex lost 4 for 1 in the middle order. Chaminda Vaas and Murali Kartik added 64 to hasten the declaration, then Kartik impressive with the ball with two wickets leaving Gloucestershire 208 behind.
