Wolverhampton Wanderers can celebrate promotion, after Fulham were held to a 1-1 draw by West London rivals Brentford.
Aleksandar Mitrovic made it 12 goals in 12 games, but Neal Maupay's last-gasp effort rescued a point and ensured the Cottagers could no longer catch the long-time leaders.

Aston Villa clinched a play-off place on Friday night with a 1-0 win over Leeds United, and Middlesbrough's come-from-behind win against Bristol City moves them to fifth, and leaves the Robins down in 11th.
Sheffield United and Millwall played out a 1-1 draw earlier in the day, a result which keeps the Lions in the top six, while the Blades remain within touching distance, three points further back.

After Shrewsbury Town drew 0-0 at Bradford City on Thursday night, the top two were also held on Saturday afternoon.
