According to De Telegraaf, Kroon had extended his contract with Saxo-Tinkoff for one year.
"I have absolutely not re-signed with the team for the new season," Kroon said on his personal website. "I still do not know what will happen."
The 37-year-old turned pro in 1997 with Rabobank and rode for CSC (2006-2009) and BMC (2010-2011) before joining Saxo Bank last year. He won a stage at the Tour de France in 2002.
