Sean Morrison's header has given Cardiff City a 1-0 lead at half time against Sheffield Wednesday.
Aron Gunnarson went close with a header from Anthony Pilkington's cross after 25 minutes but the attempt was saved by Wednesday keeper Keiren Westwood.
Cardiff striker Kenwyne Jones spurned a great opportunity to give his side the lead when he fired wide from around six yards out, moments after Gunnarson's attempt.
Craig Noone then flashed a shot wide of the goal on the half hour mark after cutting inside with a mazy dribble.
Morrison then popped up towards the end of the half with a header from Peter Whittingham's excellent corner.
