Everton midfielder Mikel Arteta has experienced a setback in his recovery from a serious knee injury.
Arteta snapped a cruciate ligament during a match against Newcastle in February and was expected to step up his rehabilitation in the next month, but the Spaniard has had to undergo a procedure to remove an infection from his right knee.
Manager David Moyes said Wednesday that "it is a setback for him. However, we can't say how long it has put him back."
