Andy Keogh's fourth goal in as many games was cancelled out by an Ian Evatt effort as Millwall and Blackpool entered the break 1-1 at the New Den this afternoon.
The Tangerines have already qualified for the playoffs but could face a two-legged tie against either West Ham United or Southampton if they lose this afternoon.
Millwall started brightly as Josh Wright shot narrowly wide and Tottenham Hotspur loanee Harry 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.
In a first half dominated by the hosts, Paul Robinson nearly doubled Millwall's advantage when his header clipped the bar.
However, Blackpool entered the break on level terms as centre-half Ian Evatt equalised for Ian Holloway's side on 27 minutes.
