West Ham have signed Wolves defender Roger Johnson on loan until the end of the season.

The former Cardiff City and Birmingham City player
had a spell with Sheffield Wednesday earlier in
2013-14 campaign.
Johnson, 30, moved to Molineux from St Andrew's
in July 2011.
Hammers manager Sam Allardyce has been backed
by the club's owners despite seeing the side slip to
19th in the Premier League and losing 5-0 to
Nottingham Forest in the FA Cup.
Central defenders James Collins and James
Tomkins were injured in the Boxing Day defeat by
Arsenal and the draw with West Brom two days
later respectively.
Fellow centre-back Winston Reid is still recovering
from ankle surgery in November, while striker Andy
Carroll has yet to play this season because of a foot
injury.
Everton's Johnny Heitinga rejected a move to West
Ham despite the two clubs agreeing terms over the
Dutch defender earlier this month.
Wolves manager Kenny Jackett transfer-listed
Johnson and three other players in June following
the club's relegation to League One, 12 months after
they dropped into the Championship.
"It's a really good opportunity for him because he's
going to a Premier League club," Jackett(external)
told the Birmingham Express and Star.
