The initial diagnosis suggests Lazio goalkeeper Federico Marchetti will be out for at least a month.

The shot-stopper was running after a misplaced pass during today’s 3-2 win away to Lecce when he suddenly pulled up.

Marchetti was clutching the back of his right leg and the initial reports suggest he has suffered a thigh strain.

If the damage is confirmed, he could be out for at least a month.
