Upson promoted from bench as Tomkins injured in Hammers warm-up
Winston Reid replaced the injured Danny Gabbidon in defence for West Ham as they looked to climb out of the relegation zone with a vital win over fellow strugglers Birmingham at Upton Park.
Matthew Upson was on the bench after recovering from tendonitis, but an injury in the warm-up to centre-back James Tomkins meant that Upson was recalled to the West Ham starting line-up.
