Kamil Zayatte put Sheffield Wednesday ahead at Elland Road with a goal shortly before half-time.
It was a tremendous boost for the Owls and manager Dave Jones.
The defender, tagged a destroyer pre-match by his fellow centre back Anthony Gardner, showed his ability at the other end to put his side in front.
Zayatte’s header led to an inquest among Leeds players over defensive reponsibilities.
After that goal Wednesday were not content to sit back, with Antonio prominent.
But early n the second half, on 58 minutes, McCormack levelled for the home side.
Antonio forced a good save from Kenny as Wednesday threatened to give Jones a great 57th birthday present.
Then Leeds sub Tonge had a long range effort blocked by Zayatte.
Wedmesday went close again from a long throw with sub Maghoma involved before Leeds survived.
They brought on Diouf with five minutes remaining but Wednesday were still looking for the victory.
Palmer, on the right, played in Coke who saw his drive blocked in the first of five minutes of added time.
