Retiring captain Stephen Craigan is expected to return to the Motherwell team for the Clydesdale Bank Premier League clash against Dundee United.
The 35-year-old announced his retirement on Tuesday and is expected to lead the team out for the final time.
The Fir Park match will be a double celebration, both of Craigan's 15 years at Fir Park and the team's Champions League qualification following their third-place finish in the Clydesdale Bank Premier League.
Craigan won 54 caps for Northern Ireland and played in two cup finals for Motherwell as well as being part of three European campaigns.
The defender, whose 378 Motherwell appearances were interrupted by a three-year spell at Partick Thistle, said: "I'm excited and I'm content with the decision I've made. It has been in the back of my mind for a few months.
"Once that thought comes in your head it's hard to get rid of. If you're having a bad day at training or struggling to get back from injury or just feeling a bit low, that thought keeps coming back.
"The emotional side I had to put to the back of my mind and try to make a logical decision that is best for me. But this weekend is going to be great. It's everything I have worked hard for, to play football for 18 years.
"It's good that it's a celebration because we are in the Champions League and have done as well as we ever have done in the SPL. That plays a little bit of a part in your decision as well. I wouldn't have liked to have finished seventh or eight in the league and say goodbye in front of 2,000 people. Ticket prices are down to £5 so hopefully it will be a good day all round."
Motherwell could rest some players who have been playing with knocks after securing third place.
Michael Higdon has been suffering from a back injury and is also one booking away from suspension so is likely to miss out.
United have doubts over several defenders with Robbie Neilson (ankle), Gavin Gunning (shoulder) and Barry Douglas (knock) are all unlikely to be risked.
Striker Milos Lacny (knee) remains on the sidelines.
The Tangerines clinched a Europa League spot thanks to last weekend's home win over champions Celticl.
United have the advantage of going in at a later stage of this season's Europa League qualifiers unlike last season when they faced Polish team Slask Wroclaw in early July.
But boss Peter Houston said: "It's not really something we've thought about that much.
"It's another great achievement by everyone to get into Europe for the third season running.
"It will probably help to have that bit more time to prepare this time round as last season's start was very early.
"However, we still have some league business to attend to this weekend when we go to Motherwell."
