Jon Toral had a goal disallowed after being ruled to have kicked the ball out of Royals keeper Vito Mannone’s hands.
After a largely uneventful first half, the Tigers came to life after the break as Jarrod Bowen went close to breaking the deadlock only to be denied by a fine save from Vito Mannone,
Allan McGregor was forced into heroics of his own when he produced an impressive stop to keep out Liam Moore’s close-range header before reacting well to push the rebound over the bar.
But it was the Tigers who had the better chances and Seb Larsson came within a whisker of finding an all-important winning goal when curling a free-kick narrowly past the wrong side of the post.
