Guedioura loaned to Hornets

The Algeria international, 29, has featured just four times for Palace in the Premier League this season.

Guedioura has also played for Wolves and Nottingham Forest and made three appearances at the 2010 World Cup in South Africa.

He could make his Hornets debut against Cardiff at Vicarage Road on Saturday.

Meanwhile, Watford's Swiss midfielder Almen Abdi could also be in contention to face the Bluebirds.

The 28-year-old has been out since last month with a shoulder injury but proved his fitness by playing an hour for the club's Under-21's on Tuesday.
