Motherwell could be set to lose Kevin van Veen with the striker reportedly due to have a medical with Groningen.
The Dutch club previously admitted their interest in the 32-year-old forward, who netted 29 goals for the Steelmen last season.
The potential transfer could bring in £500,000 for the Lanarkshire club.
Motherwell announced the signing of forward Jon Obika on Monday following his loan spell in the second half of last season.
The 32-year-old former St Mirren and Morecambe striker scored once in 10 appearances.
“Having been here last season, I was really eager to come back again this season,” Obika told Motherwell’s website.
“I thrive when I work in a professional environment and feel that’s when I can get the best out of me. This club has high standards in abundance and I’m fully committed for the campaign ahead.
“There is a real feel-good factor at the club and I’m looking forward to trying to create a successful season together.”
