The top two in the Championship remain unchanged after their draw, while Brentford are third and Stoke City thumped Huddersfield Town.
Leeds United remain top of the Championship after a 1-1 draw with West Brom at The Hawthorns on Wednesday.
Semi Ajayi put the Baggies ahead in only the second minute but was unfortunate in deflecting Patrick Bamford's header into his own net to bring Leeds level.
The result means Marcelo Bielsa's side stay above West Brom on goal difference after 26 matches.
The earlier fixtures were largely a feast of goals as 2020 started in enthralling fashion, with Stoke City winning 5-2 at Huddersfield Town and QPR thrashing Cardiff City 6-1.
Brentford were big winners away to Bristol City, Nottingham Forest edged out Blackburn Rovers in a five-goal thriller and Wigan Athletic held on to win 3-2 at Birmingham City.
Fulham's promotion bid suffered another setback with a 2-1 loss to Reading, Middlesbrough made it back-to-back away victories and Hull City snatched three points at Sheffield Wednesday.
In the first game of the new decade, Millwall came from behind to beat Luton Town 3-1 and climb into the top six.
BAGGIES MISS CHANCE TO GO TOP
Ajayi poked home after a penalty-box scramble to give West Brom an early lead against Leeds and Slaven Bilic's side were good value for their advantage in the first half.
Kiko Casilla did superbly to keep out Matheus Pereira's free-kick and then saved with his legs from Matt Phillips, who had been through on goal.
Leeds introduced Bamford at the break and it proved a crucial move, as the striker's header from Jack Harrison's cross deflected off Ajayi's shoulder and into the net.
Neither side could find a winner in the end-to-end closing minutes, meaning each are on 52 points, nine clear of the chasing pack.
Stoke dominated the first half at John Smith's Stadium but Sam Vokes' opener was forgotten when Steve Mounie and a Danny Batth own goal put the hosts ahead.
However, Stoke struck a further four times through Nick Powell, Lee Gregory and a Tyrese Campbell double in a game otherwise marred when a stadium announcement was required to warn against further alleged discriminatory chants aimed at James McClean.
QPR's victory was a more straightforward affair, as a Nahki Wells hat-trick inspired them to a 6-1 thrashing of Cardiff, who got a late consolation through Will Vaulks.
Cardiff stay 12th, though, given Bristol City were dispatched 4-0 at home by Brentford, Ollie Watkins making the points safe with a late double to send his side third.
MILLWALL INTO PLAY-OFF SPOTS
Sheffield Wednesday's loss at home to Hull meant Millwall's earlier 3-1 win over Luton, in which they trailed until the 69th minute, was enough to see them into the top six.
Nottingham Forest are up to fourth thanks to Lewis Grabban's two goals securing a 3-2 defeat of Blackburn Rovers, with Fulham slipping to fifth after John Swift and Charlie Adam consigned them to a fourth defeat in seven league games.
Preston's top-six chase was dealt a blow, though, as Rudy Gestede and a Ben Davies own goal gave Middlesbrough a fourth win in a row.
At the other end of the table, Wigan gave their survival bid a boost after they held onto a 3-2 win at Birmingham, Cedric Kipre's 73rd-minute goal proving the difference.
