Leicester City have extended the loan deal of Manchester United defender Michael Keane until the end of the January transfer window.
Keane joined the Championship club in early November, but he has been restricted to just two appearances for Nigel Pearson's side.
The 19-year-old picked up an injury on his debut against Bolton Wanderers before returning to the team for the New Year's Day thrashing of Huddersfield Town.
He is now eligible for Leicester's FA Cup third round tie against Burton Albion on Saturday and the club's next four matches in the Championship.
The centre-half has made three appearances during his United career, all of which have been in the League Cup.
Sheridan has been out of management since leaving Chesterfield in the early weeks of this season, but is understood to have been interviewed by Plymouth on Friday.
Bookmakers have suspended betting on the next boss at Home Park and reports suggest Sheridan's appointment will be confirmed on Monday.
Plymouth have moved quickly to install a new man at the helm after dispensing with Carl Fletcher earlier this week following a run of one win in 13 League Two fixtures.
Fletcher, who had been in charge since September 2011, left the Pilgrims in 21st position in the table, just two points outside the relegation zone.
Former Leeds United and Sheffield Wednesday midfielder Sheridan won the League Two title with Chesterfield in 2010/11 but his challenge now is to keep Plymouth in the Football League.
