Leighton has appeared in seven games this season, putting up a 1-4-0 record with a 4.28 goals against average.
This is Leightons second go with the Flyers.
He appeared with the team during the 2006-2007 season, in which he went 2-2-0 with a 3.69 goals against average.
In his sixth seasons with the NHL, Leighton is 18-35-12.
This should help the Flyers, who needed a backup goalie due to the injury to starter Ray Emery.
