Ronald Koeman fears Morgan Schneiderlin could be out of action for “several weeks” with a calf injury sustained against Hull City.
The Frenchman was forced off after 30 minutes in Saturday’s 4-0 win over the Tigers at Goodison Park.
Koeman says Schneiderlin will undergo a scan on Sunday to ascertain the severity of his injury.
“We need to make a scan tomorrow, it’s his calf,” Koeman said. “I’m a little bit worried he might be out for several weeks but we need to wait until tomorrow."
