Middlesbrough are guaranteed a place in the Sky Bet Championship play-offs after goals from Britt Assombalonga and Jonny Howson secured a 2-0 win over Millwall.
Boro have booked their play-off place with a game to spare, although the identity of their opponents will not be clear until they have completed their campaign at Ipswich next weekend.
Millwall still have a statistical chance of claiming a play-off place, although in reality their hopes are gone as they would need a nine-goal swing to overhaul Derby on goal difference even if they were to win their final game against Aston Villa and both the Rams and Preston were to lose.
