The Belgian winger, 27, was stretchered off after being fouled by Jordon Mutch towards the end of Everton's 3-1 home win in the Premier League on Monday, in which he scored, and underwent scans on Tuesday.
"We are still doing some tests and nothing is conclusive yet," Martinez told the Everton website.
"It's clearly ankle damage and we are not going to find out until the next two or three days the extent of the injury."
