Winger Feeney helped breathe new life into Dougie Freedman's struggling side earlier this term as part of a triumvirate of loan recruits which included full-back Kevin McNaughton and midfielder Neil Danns.
While the latter two remain at the Reebok Stadium, Feeney was recalled from his three-month stay with parent club Millwall at the end of October, much to the disappointment of Spearing and his team-mates.
The Lions visit Bolton, who are still looking for their first home win of the season, this weekend and the hosts know they will have to prepare for a man who helped kickstart their current six-match unbeaten run.
Speaking after being named Championship Player of the Year at the Northwest Football Awards, Spearing said: "He was a great lad, he did wonders for Bolton.
"The lads got on with him really well and we were all devastated that he left, sometimes that's what happens in football.
"If he plays Saturday we'll show him the respect but hopefully he won't be scoring any goals."
