Norwich were involved in a seven-goal thriller at Copers Cope Road.

Kick-off was delayed by 15 minutes due to a traffic incident around the Blackwell Tunnel approach, but that was the least of manager Ricky Martin's worries, who was yet again hit by injuries and unavailability.

Norwich opened the scoring on six minutes when Jason Dobbs lifted the ball from the right into the Palace penalty area and Sam Habergham hammered it past keeper Charlie Mann.

City pressed for a second as Palace tried to come to terms with the early setback and on 18 minutes only a late intervention denied Jamar Loza from applying a finishing touch, before Matt Ball shot wide.

City keeper Jed Steer was almost caught out with a surprise effort, but two minutes later an almost identical strike did find the back of his net, as Kyle De Silva, from fully 25 yards, levelled the score.

And just as Norwich thought they had weathered a Palace storm, Remy Gordon conceded a penalty on 32 minutes, bringing down pacy winger Rhys Williams. Ibra Sekajja completed the honours from the spot.

Ball got on to the scoresheet five minutes into the second half with a quality effort which went in off a post from 18 yards to make it all square again.

But Palace were ahead seven minutes later, picking up the loose ball after an accidental intervention by the referee in midfield. Sekajja sprinted away on the right flank before moving infield and shooting over Steer from an acute angle.

City skipper Ball went close, but on 65 minutes De Silva got behind the Norwich defence and raced away, before drawing Steer from his line to make it 4-2.

Loza - a constant threat - pulled one back after a good, strong run from the centre circle - but Palace keeper Mann twice saved his side as City went for the equaliser.

First, on 73 minutes, he tipped over a Gordon free-kick from outside the area and three minutes later produced the save of the match, stretching full length to palm away Loza's shot.
