Leicester City are on course for three points that could see them top the Championship, after edging in front at home to Millwall.
The Foxes took the lead after 12 minutes when Marcin Wasilewski played in Danny Drinkwater, and his deft chip was met by Lloyd Dyer's volley for his sixth goal of the season.
Millwall's best chance of the half fell to Mark Beevers, who volleyed over from 12 yards out.
However, the hosts came close to doubling their lead when David Forde spilled Anthony Knockaert's shot, but Jamie Vardy was unable to take advantage.
Leicester started the game one of three sides tied on 35 points at the top of the Championship table, trailing Burnley on goal difference.
