Chesterfield manager Roy McFarland has boosted his front line with the signing of ex-Derby County striker Marvin Robinson on a short-term deal.
Marvin Robinson, once with Derby, holds off David Beckham
The 23-year-old, released by the Rams in May, has signed a two-week contract at Saltergate.
The Spireites, bottom of the Second Division and without a win this season, are already without forwards David Reeves and Glynn Hurst through injury.
Earlier this week, on-loan Mark DeBolla returned to Charlton after he tore ankle ligaments on his debut against fellow strugglers Notts County.
"This short-term signing is of mutual benefit to both the club and the player," said McFarland.
"It means we can take a look at each other before we make a decision about the future, while it also gives us a fresh face at a time when the squad is a little depleted through injury."
Meanwhile, Chesterfield have released defender Damon Searle, who had been on a monthly contract.
