Everton will assess defender Yerry Mina before tomorrow's Premier League clash against Watford.

Mina (foot) has sat out the last three games and boss Marco Silva - who will be making his first return to Vicarage Road since being sacked by Watford last season - said the defender's involvement was still in doubt.

Leighton Baines (rib) and Phil Jagielka (knock) are definitely still unavailable. The likes of Richarlison and Gylfi Sigurdsson may be restored to the starting XI after dropping out of it for Wednesday's 2-0 loss to Manchester City.

Provisional squad: Pickford, Keane, Zouma, Digne, Kenny, Gomes, Gueye, Davies, Bernard, Walcott, Calvert-Lewin, Stekelenburg, Coleman, Sigurdsson, McCarthy, Schneiderlin, Tosun, Richarlison, Lookman, Mina.
