Albert Riera has been charged by the FA with improper conduct during Watford's 3-1 defeat at Charlton on Tuesday evening.

The Spaniard was dismissed in the 81st minute after collecting two bookings and it is alleged his behaviour following the incident amounts to improper conduct.

In being sent off at The Valley, Riera became the sixth Hornet to see red in Beppe Sannino's 28 games in charge this season.

Riera has until 6pm on May 6 to respond to the charge.
