Premier League hopefuls Blackpool were denied by a late Harry Kane goal as Millwall fought back to earn a 2-2 draw at the New Den this afternoon.
Millwall started brightly as Josh Wright shot narrowly wide and Kane forced a good save out of visiting goalkeeper Matt Gilks.
The Lions' early chances were rewarded when Keogh calmly slotted past Gilks following good work from James Henry.
Against the run of play, Blackpool then equalised on 27 minutes when Ian Evatt headed in from Stephen Crainey's cross.
The match was a more even affair from then on and the visitors could have even gone into the break in front as Thomas Ince's free kick went narrowly over the bar.
Crainey was again the provider as Nouha Dicko put Ian Holloway's side ahead on 70 minutes by converting the Scot's pass from inside the six-yard box.
However, Millwall replied as Tottenham Hotspur loanee Kane struck low into the bottom corner from outside the box to earn the Lions a point.
The Tangerines will now face Birmingham City in the playoff semi-finals.
