Nahki Wells and his promotion chasers Huddersfield teammates closed the gap on the Sky Bet Championship top two to six points with a hard fought 1-0 win at Brentford.
Rajiv van La Parra's freak goal just before the half-hour mark was the difference between two good footballing sides.
Brentford's defense fell asleep and - when a quickly-taken free-kick found Van La Parra wide on the left - the Dutch winger's fierce cross-shot was punched into the net by Bees goalkeeper Daniel Bentley for a winner that may have the dubious goals panel scratching their heads.
Midway through the first half, Tommy Smith was getting plenty of joy down the Brentford left flank and teed up Wells with an inviting near-post cross which the livewire striker side-footed against the upright.
Shrewsbury took another step closer to safety with a 1-1 draw at Rai Simons’ Chesterfield which pushed the home side nearer to relegation.
Tyler Roberts scored his fourth goal since he moved from West Brom on loan but Ian Evatt leveled for Chesterfield before he was carried off injured.
Simons was an unused substitute in the match.
Medy Elito's second-half hat-trick condemned Reggie Lambe and his Carlisle united teammates to a fourth straight defeat as Cambridge ran out 3-0 winners at Brunton Park.
The Cumbrians' automatic promotion hopes took another hit as they conceded two penalties before having James Bailey sent off in stoppage time.
Half-time substitute Elito, who had three goals in 19 U's appearances going into the game, scored both spot-kicks and secured the match ball with a strike five minutes into added time.
