Manchester City attacker Kevin de Bruyne is set for a scan tomorrow.
De Bruyne was forced off in the first-half of Friday night's win at Burnley.
There's fears the midfielder has aggravated a long-standing hamstring injury and management will know more after Monday's scan.
After the win, Guardiola said: "It depends on the magnitude of the injury but he will be out for a few weeks.
"He is down. We have to reflect, talk to the doctors, see what happened. He has to be relaxed, recover and come back."
