David Sales joins Northants' growing injury list
Northants have lost David Sales to injury ahead of their County Championship match against Yorkshire.
The former skipper has torn a hamstring and will be out for up to six weeks, which could rule him out of the entire Twenty20 campaign.
He joins Chaminda Vaas, Jack Brooks, Rob Newton, Ben Howgego, Luke Evans and Sam Sweeney on Northants' injury list.
Sales was injured whilst running a quick single in the County Championship match against Gloucestershire.
