The defender’s first-half header for the Tigers was cancelled out by Peter Whittingham’s close-range effort in the second half.
The Tigers dominated in the early stages with the impressive Sone Aluko firing a curling effort inches wide. And that dominance was rewarded on 39 minutes when Davies nodded in Tom Huddlestone’s cross from three yards out.
The Bluebirds improved after the break and equalised when Whittingham finished off a slick one-touch passing move to stroke the ball in. Aron Gunnarsson should have made it 2-1 minutes later but he planted his header wide from Gary Medel’s cross.
Hull finished strongly with Aluko having a goal ruled out for off-side after putting in Stephen Quinn’s cross but both sides shared the spoils.
PRE-MATCH: Joe Lewis makes his Premier League bow for Cardiff to replace the injured David Marshall
5’ - MISSED CHANCE FOR HULL: Graham has missed a sitter from three yards out after Aluko's shot is parried - his goal drought continues.
15’ - PENALTY SHOUT FOR CARDIFF: Campbell flashes a shot across goal from the right-hand side after Kim went down in the box after some contact from Koren but the ref waves play on.
25’ - ALUKO GOES CLOSE: Aluko fires a shot high into the side-netting after a good run into the box from the left-hand side.
39’ - GOAL! Good cross from Huddletone on the right and an unmarked Davies nods in from three yards out.
59’ - EQUALISER! Sweeping move involving Campbell and Medel and Whittingham taps the ball in from three yards out, great first-touch football.
78’ - DISALLOWED GOAL: Aluko puts the ball in the net but is ruled out for off-side after a great ball into the box by Quinn.
Cardiff have failed to win in their last 15 top-flight away matches, since a 1-0 victory at Fulham in the old Division One in November 1961.
There have been at least two goals scored in the last 7 matches between the teams.
TALKING POINT - Is Lewis ready for England? Joe Lewis will inevitably get linked to an England call-up after an impressive debut with a strong command of his box.
