Leicester 1 Albion 2
Graham Dorrans and Gonzalo Jara struck from distance to give Albion an impressive victory at the Walkers Stadium.
Dorrans drilled a low free-kick through a group of bodies on 36 minutes and Jara lashed in a vicious shot for his first goal in English football five minutes before half-time.
That made him the 15th different Albion scorer this season and the superb Chilean played his part in a fine rearguard effort, as the Foxes applied the pressure late on and scored through Bruno Berner.
Albion dominated the opening half-hour but their best two chances fell to Luke Moore, who was unable to convert.
First the striker latched on to a fine through-ball from Graham Dorrans and peeled away from Wayne Brown but delayed his shot, allowing the left-back to make up lost ground and make a timely block.
Moore had an even better chance on 18 minutes. Chris Brunt, who was recalled in favour of Filipe Teixeira, lofted the ball down the line to the feet of Gianni Zuiverloon.
The Dutchman beat Brown and pulled the ball back for Moore, but the striker sent his shot too close to goalkeeper Chris Weale.
Leicester began to find their feet, only to be stunned twice in the final nine minutes of the first half.
First Matthew Oakley fouled Jerome Thomas 20 yards out and Dorrans struck a low free-kick that looked to take a slight deflection past Weale.
Four minutes later Jara was given too much space to stride into the Leicester half a whack an unstoppable shot past the home goalkeeper.
But Leicester should have been level within a minute of the restart, as Matty Fryatt got the better of Jonas Olsson and Jara to cross for the unmarked Paul Gallagher, who missed a sitter from a couple of yards.
Albion could have wrapped up the win before the hour-mark but Brunt send a tricky header wide from Dorrans' free-kick, while Weale turned a Jerome Thomas shot around the post.
But the Foxes piled on pressure late on as they searched for a way back into the match and Albion were forced into some resolute defending.
Moore was denied a goal with 11 minutes remaining when his clever lob from just inside the box beat Weale but hit the bar.
The home side did pull one back four minutes into stoppage time, when goalkeeper Scott Carson could only parry Gallagher's free-kick and Berner forced home the rebound.
