The Republic of Ireland striker missed last weekend’s 2-1 win at Burnley due to “personal reasons”, but boss Graham Potter has revealed those concerns have been resolved.
Forward Danny Welbeck and full-back Tariq Lamptey remain sidelined with hamstring problems. Defender Joel Veltman will miss out due to self-isolation.
Adam Lallana, Jakub Moder and Alexis Mac Allister all impressed from the bench at Burnley and are pushing for starting roles against a Watford team who beat Aston Villa 3-2 last Saturday.

Will take his place in the centre of the Albion midfield
7. Enock Mwepu
