Livingston have opened talks with Celtic about the possibility of bringing former favourite David Fernandez back to the club on a one-year loan deal.
David Fernandez has rarely featured in a Celtic jersey
The West Lothian outfit have already made space for the Spaniard in their squad, having allowed Davide Xausa to leave for Falkirk.
Fellow forward Fernandez left Livingston for Celtic Park in a £1m deal in June 2002 but has seldom featured in manager Martin O'Neill's plans and scored just one goal last season.
Livingston chairman Dominic Keane told the club's website said: "We'll have further discussions with Celtic Park over the next few days in an attempt to agree a deal before the transfer window closes at midnight on Sunday, but we're hopefull that a deal can be concluded before then.
"However, even if those negotiations are successfully concluded before then, David will definitely not feature for Livingston during this Saturday's visit to Parkhead."
Meanwhile, Xausa became Falkirk's second signing in two days, having secured the signature of midfielder John O'Neil from Hibernian.
Falkirk will hope that Canadian international Xausa will repeat the fine form he showed previously in the First Division with Inverness Caledonian Thistle then Livingston.
Xausa, who still had one year left on his contract at the City Stadium, had fallen down the pecking order with the West Lothian side following the arrivals of Derek Lilley and Guy Impoua over the summer.
