Saints manager Nigel Pearson was forced into the emergency loan market for the 30-year-old former England international after he lost three goalkeepers in a month to freak injuries.

First-choice keeper Kelvin Davis dislocated a finger when he caught it in another player's shorts, and Bartosz Bialkowski is out for the season after he was kicked on the thumb by a team-mate.

Michael Poke, only recently recalled from a loan spell at non-league Torquay, then suffered an ankle-ligament injury during the warm-up ahead of Saints' 5-0 defeat at Hull City - although he bravely completed the match.

Wright, who is second choice to Robert Green at Upton Park and has made just three Carling Cup appearances this season, is set to make his debut against Coventry City on Saturday.

Pearson said: "I am delighted to have got Richard. He is a proven goalkeeper with plenty of experience.

"It is a bizarre run of injuries but there is no point being negative. We had to address the situation and I am very pleased to have Richard on board."
