Leicester City missed the chance to go level on points with second-placed Manchester United as they drew 0-0 at Wolverhampton Wanderers.
Wolves started brightly, with Ruben Neves firing over on 11 minutes before Adama Traore, who caused problems with his pace and skill throughout, had a shot deflected wide by James Justin.
Leicester finished the first half on the front foot, as a neat one-two between Harvey Barnes and Kelechi Iheanacho set up James Maddison, but Jonny twice made important blocks in quick succession.
Two substitutes had great chances to earn victory. Firstly, Wolves' Fabio Silva had a close-range shot brilliantly saved by Kasper Schmeichel.
Then Jamie Vardy came off the bench on his return from injury and headed wide in stoppage time.
Leicester remain in third place on 43 points, two behind Man Utd, while Wolves stay in 14th with 27 points.
