Leeds United and Blackburn Rovers have gone into half time level after neither side could break the deadlock in the first 45 minutes.
The first real chance fell to Rovers' Jordan Rhodes, as his shot was deflected onto the bar inside a quarter of an hour.
Another good chance fell to Rhodes again, after Leeds's Sol Bamba's clearing header fell to the striker, with his effort being tipped over.
The home side were reduced to 10 men shortly before the half-time whistle, as Rodolph Austin was sent off for violent conduct in an off-the-ball incident.
