Hull City conceded two goals in the first 10 minutes against Chelsea but rallied with two quickfire strikes of their own to take a 2-2 scoreline into the break at the KC Stadium.
The visitors emphatically took the lead within the first two minutes when Diego Costa set up Eden Hazard 35 yards from goal, with the Belgian travelling forward before rifling the ball across Allan McGregor and inside the far post.
Just eight minutes later, the Blues were two goals to the good, with Costa collecting Cesc Fabregas's ball before marauding forward unopposed and curling into the net.
Far from giving up, Hull fought back and halved the deficit in the 27th minute when Andrew Robertson whipped a ball into the Chelsea box for Ahmed Elmohamady to scramble home from close range.
Steve Bruce's charges did not have to work particularly hard to get themselves level. Just a minute later, Thibaut Courtois tried to control a Branislav Ivanovic ball onto his left foot, but passed it straight to Abel Hernandez, who slid home into the empty net.
Chelsea were then under the cosh for the remainder of the half as David Meyler and Gaston Ramirez dragged a number of chances wide of goal, but Hull could not capitalise on their momentum to take the lead by the break.
