Rochdale 0-0 Northampton
A new-look Rochdale side could not break down the stubborn Northampton defence in a goalless draw.
The hosts had six players making their league debuts, but were under pressure early on as the Cobblers bombarded their area with a string of set-pieces.
Ashley Grimes, George Donnelly and Phil Edwards all went close for the Dale.
After the break, Peter Cavanagh continued the threat with a diving header, while Alex Nicholls wasted a good chance for the visitors.
