MK Dons 0-0 Crawley Town
Veteran striker Ryan Lowe had three goals ruled out for offside as MK Dons' faint play-off hopes took a major blow.
They dominated the first half as Lowe hit the net with a header and a tap-in and he then fired home from close range after the break, only to be flagged offside again.
Crawley were a threat on the break with striker Billy Clarke, who twice missed the target when well placed.
MK ended seven points off the top six, with Crawley three points further back.
VIEWS FROM THE DRESSING ROOM
MK Dons manager Karl Robinson told BBC Three Counties Radio:
"I've got a lot of respect for Richie Barker and his team, but I think we pummelled them today. We've got to more clinical and we understand that.
"I think we could not do any more than what we've done. It's a more dominant performance than you're going to see anywhere up and down the country.
"We're not out of it [play-off contention]. Simple as that. It's no holds barred now - we've got to win the (remaining) games."
Crawley Town manager Richie Barker told BBC Sussex:
"It wasn't through a lack of spirit and hard work. It was a very patched-up team, thrown together, and I thought the second half [display] was excellent.
"I think that's probably the first game in about eleven we've not dominated. It's nice we've come away in a different way and picked up a point.
"As the game went on you could see them rallying each other on. We made sure we had a clean sheet and to be fair they kept going."
