Norwich City and Leeds United played out a goalless draw in the first leg of their Championship play-offs semi-final tie as both teams seek a return to the Premier League.
Leeds appealed for a penalty in the seventh minute when Willy Gnonto went down after contact with Borja Sainz on the edge of the penalty area but the referee disagreed, awarding a goal kick instead.
Junior Firpo found the net on the half-hour mark but Georginio Rutter was offside during the build-up, causing the goal to be ruled out for the visitors.
Norwich, who failed to score at a home game for the first time since December, will visit Leeds for the second leg of the semi-final on Thursday.
