Gregg to join NorthamptonLions winger Gregg Wylde is set to join Northampton Town on a standard loan until the end of the season from 1st January.
Gregg, who has made just 10 appearances for Millwall since joining from Plymouth in the summer, will not be eligible to play for The Cobblers when the sides meet at The Den on Good Friday.
Also going out on loan is young keeper Harry Girling, who will re-join Welling United on a youth loan, having returned to The Den from Park View just last week.
Lions boss Neil Harris said: "Gregg hasn't been involved as much as he would have liked of late and naturally he wants to play games, so this move will give him the opportunity to play regular football."
