Palace boss Trevor Francis is expected to make at least one addition to his squad in the coming weeks, after he moved to trim the squad this week.
Loan signing Trevor Benjamin has returned to Leicester City on a permanent basis after he failed to impress during a month long spell.
Palace were keen to extend his loan spell until last week, but two lacklustre performances from the burly target-man and an injury to Leicester's Brian Deane meant he has gone back by mutual
The 22-year-old scored one goal against Bradford City in six games for the Eagles.
Francis will now look to bring in another target-man.
Palace's other loan signing Christian Edwards also returned to his club Nottingham Forest after six weeks at Selhurst Park. Edwards, 26, played nine games with mixed success, but the return of
Tony Popovic from injury, and the signings of Curtis Fleming and Danny Granville meant he was surplus to requirements.
Palace's Latvian winger Andrejs Rubins has joined French club Troyes on a week's trial with a view to a permanent deal.
Best remembered for his goal against Liverpool in the Worthington Cup semi-final last year, Rubins, 24, fell out of favour when Steve Bruce arrived in the summer.
He has made just six appearances this season, as the emergence of Julian Gray has limited his opportunities.
Trevor Francis will let him leave Selhurst Park for a nominal fee. The Eagles manager will now look to bring in a centre forward and a midfielder to boost the Eagles promotion campaign.
