DUNDEE UNITED are 1-2 favourites to reach the Premiership play-off semi-finals but may have to settle for a draw in Greenock tonight.
It was 1-1 at Cappielow on Saturday as the regular season finished and over the whole campaign the sides can't be split.
They've met five times, drawn the last three and each side has won 2-1 at home.
Another stalemate tonight pays 12-5 at Marathonbet and a third 1-1 in a row is 6-1 with McBookie.
Morton are 13-5 at Paddy Power to take a lead to Tannadice on Friday with the Tangerines 13-10 at Marathonbet.
It's bound to be tight and tense and I'd favour under 2.5 goals at 43-50 with Marathonbet.
To qualify, with Falkirk awaiting the winners, Morton are a best evens at Marathonbet but I'm on United to edge it over two legs.
