Motherwell have decided against signing Adam Czerkas, despite the Polish striker scoring in a 3-0 victory over Lech Poznan in Austria.
Mark McGhee is looking to make new signings at Fir Park
But compatriot Robert Gubiec could be given another chance to press his case to be Well's new goalkeeper.
Manager Mark McGhee told his club website: "The centre forward was not what we are looking for.
"And the keeper we will be discussing again to decide if we want another look at him before the season starts."
The 28-year-old Gubiec, previously of Legia Warsaw, Agrykola Warsaw, Polonia Warsaw and Ostrowiec Swietokrzyski, played for 45 minutes in both the win over Lech and the defeat by Dinamo Bucharest.
To allow some to come in, others will have to go out

Czerkas, available from Korona Kielce, made an immediate impact after coming on as a substutite against Lech, driving home Motherwell's third goal.
But the 23-year-old, who had been loaned out to Queen's Park Rangers and Odra Wodzislaw last season, did not do enough to impress the Scottish Premier League outfit.
McGhee was, however, delighted with the latest workout as the new manager assesses his squad.
"Some have impressed me that I wasn't expecting and others are not quite as good as I was led to believe," he said.
"One or two may not be able to go on and do it and there will be casualties as we look to establish a squad of 22-23 players as we cannot afford to carry a squad of 28.
"Therefore, to allow some to come in, others will have to go out."
