Defender Alex is expected to sit out Chelsea FC's UEFA Champions League Group F game at FC Spartak Moskva on 19 October because of a thigh muscle injury.
The 28-year-old centre-back sustained the injury in the closing stages of Sunday's 2-0 home victory against Arsenal FC after scoring Chelsea's second goal and has since withdrawn from the Brazil squad to face Ukraine on Monday. "It is estimated he will be out for three weeks," a club statement read.
English titleholders Chelsea are level with Spartak at the top of Group F after winning their opening two matches, against MŠK Žilina and Olympique de Marseille.
