Motherwell boss Ian Baraclough insists the tie is not over after watching the Steelmen beat Rangers 3-1 at Ibrox in the Premiership play-off final first leg on Thursday.
Motherwell have been in the top-flight since 1985 while the Gers, looking for their third promotion in a row, have already had to beat Queen of the South and Hibernian in the play-offs.
Baraclough's side finished 11th in the Premiership, while Stuart McCall's side were third in the Championship, behind Hearts and Hibs.

Lee Erwin and Stephen McManus scored first-half goals for Motherwell before Lionel Ainsworth made it 3-0 early in the second half. Darren McGregor grabbed a late goal for the hosts but Rangers have it all to do if they are to secure a place in the top-flight.
The second leg is set to be played at Fir Park on Sunday. Rangers are 1/1 to win the match 3-0, while a 1-1 draw is available at 1/1.
"This tie is not over," said former Scunthorpe United boss Baraclough. "Nobody is getting ahead of themselves. We need to put in another 95-minute shift. That's probably the best performance in my time and we'll need to produce another one on Sunday.
"We'll need to be controlled and calm to make sure we get the job done.
"It was a fantastic performance. We came here with a game plan; we knew we could hurt them with our pace on the counter-attack. Everyone showed what they can do."
