Plymouth are hoping to extend Russell Anderson's loan deal from Sunderland for another month.
The Scottish international defender joined the Pilgrims on an initial month-long deal in February and has made six appearances for Paul Sturrock's play-off chasing side.
His current agreement at Home Park is due to expire after Saturday's visit to Championship leaders Bristol City, but discussions are already underway to prolong his stay.
He has made just two appearances for Roy Keane's Black Cats since a summer move from Aberdeen, but has proved his international pedigree during his brief spell on the coast.
"We have chatted to Sunderland and we are just waiting on a word back," Sturrock told Plymouth's official website.
"He has done okay for us and he would be a benefit but it is purely in Sunderland's hands at the minute.
"We have been in discussions and we will wait and see what transpires.
"His performances have been consistent. He has been a steady Eddie for us and never let us down."
