Rasiak joined on loan from Southampton earlier this month

Watford's on-loan Polish forward Grzegorz Rasiak will be out of action for between four and six weeks after breaking a bone in his shoulder.

Rasiak suffered the injury during his debut against Charlton on 16 August, yet played during Saturday's 3-2 defeat at Nottingham Forest.

The 29-year-old, on-loan from Southampton, will be rested on the advice of the club's medical staff.

Watford are already missing forward Theo Robinson with a fractured arm.
