Andros Townsend's first-half goal saw Luton beat Newcastle 1-0 at Kenilworth Road to boost their Premier League survival hopes.
Eddie Howe's visitors were made to look ordinary by a side tipped widely for the drop.
The winner came during Newcastle's only spell of sustained first-half pressure as Luton's star pair of Townsend and Ross Barkley combined at a corner.
The gap to safety now stands at just two points after a third victory on the Hatters' top-flight return.
Luton had laid out the kit of captain Tom Lockyer in their dressing room, seven days after he suffered a cardiac arrest that forced the abandonment of their game against Bournemouth. The 29-year-old's name rang around the ground throughout.
Dominic Solanke completed a last-gasp hat-trick to earn Bournemouth a 3-2 win at Nottingham Forest and ruin Nuno Espirito Santo's first game in charge at the City Ground.
Forest had looked like overcoming the controversial first-half red card of Willy Boly to earn a worthy point after Chris Wood had headed them level in the 74th minute.
But Solanke, who had earlier scored twice in seven minutes to overturn Anthony Elanga's opener for Forest, broke their hearts when he headed home in the fifth minute of time added on.
Forest will have grave complaints about the 23rd-minute dismissal of Boly, who was sent off for two yellow cards, with referee Rob Jones brandishing the second despite the defender clearly winning the ball.
Nuno, who replaced the sacked Steve Cooper earlier in the week, will be enthused by what he saw from his side, but he has inherited a relegation battle and Forest could be in the bottom three if results do not go in their favour in the St Stephen's Day fixtures.
Life is much better for the Cherries, who won for the fifth time in six matches to climb into mid-table and Solanke took the matchball home for the first time in his career.
Burnley scored two superb goals to give Vincent Kompany's side a deserved victory over Fulham at Craven Cottage.
Two long-range strikes from Wilson Odobert and Sander Berge gave Burnley their first win since December 2.
The 2-0 score-line meant a second straight league defeat for Marco Silva's Fulham following last week's 3-0 setback at Newcastle.
The match saw Rebecca Welch make history by becoming the first female referee to officiate in the Premier League.
