Motherwell manager Stuart McCall will continue his search for a striker after David Clarkson failed to win a return to Fir Park.
The 28-year-old had been training with the Lanarkshire men after leaving Bristol Rovers.
"David is no longer with us," McCall said. "He trained well and is a decent lad, but he's not exactly what we're looking for.
"We're looking for someone with pace to go in beyond."
McCall remained upbeat about Motherwell's Europa League second qualifying round chances despite a 2-0 friendly defeat by Fulham at Fir Park.
Cameron Burgess and Kostas Stafylidis hit the net for the Cottagers, but McCall was happy with the workout ahead of hosting Icelandic side Stjarnan in Thursday's first leg.
"Obviously you don't want to lose but we played some nice stuff," said the manager.
"The bigger picture is that it's another 90 minutes under the belts which we needed prior to Thursday."
Stjarnan eased past Welsh side Bangor City 8-0 on aggregate in the first qualifying round and are also halfway through their season.
"We haven't discussed them too much but certainly come Thursday everyone will know about their strengths and weaknesses," McCall told the Motherwell website.
"When I was a player I always wanted three or four 90 minutes under my belt before we got into the league season, which the lads will have had once the league season starts.
"Obviously we'd rather be involved in Europe than not, but it does come around early. That's not an excuse.
"The lads have got a good level of fitness, match sharpness is a little bit different. The team we face are halfway through the season now.
"I've seen them down at Bangor and I've seen a couple of DVDs of them. They've got three or four players middle-to-front that can cause problems, good players.
"We feel we can exploit some defensive weaknesses and we'll need to be at our best to do that but we're looking forward to the game."
