The 29-year-old Poland international has made 61 appearances for the Red Devils since arriving in summer 2006 but has not featured for the first team this season, with David De Gea and Anders Lindegaard the first two choices between the posts for manager Sir Alex Ferguson following Edwin van der Sar's retirement.
Kuszczak started his professional career with Hertha Berlin and moved to England in 2004 when he signed for West Brom. He switched to Old Trafford in July 2006, initially on loan from the Baggies before penning a permanent deal the following summer.
Kuszczak will battle for the gloves with former England Under-21 keeper Scott Loach, who has played in 31 of the Hornets' 35 games so far this term.
