Crewe Alexandra have signed striker Greg Pearson on a month-long loan from League Two rivals Burton Albion.
The 26-year-old recently returned from a four-week spell at Aldershot, where he made just one start and five appearances as a substitute.
Burton boss Paul Peschisolido wants Pearson, who was sidelined by a toe injury earlier in the season, to get more first-team action at another club.
Pearson will go straight into the squad for the trip to the Kassam Stadium, as both Shaun Miller (hamstring) and AJ Leitch-Smith (thigh) have both been ruled out because of injury.
The former West Ham trainee scored 18 goals as Burton were promoted from the Blue Square Premier in 2008-9 and then netted the Brewers' first ever goal in the Football League.
But Pearson's injury, plus the form of Billy Kee, Justin Richards and Calvin Zola, has left him short of first-team football.
