KRIS Twardek, Kyron Farrell, Chris Parr and Jamie Philpot have signed their first professional contracts at Millwall.
The young quartet join the senior ranks at the club after agreeing one-year deals.
Philpot has scored regularly for the Lions' youth teams this season, finding the net 14 times in his combined appearances for the U18s and U21s.
The striker, above, was on the bench for the first team at Brentford in March and could be included in the squad to face Wolves this weekend.
Midfielders Farrell and Twardek have both been involved at international level for the Republic of Ireland and Czech Republic respectively.
Parr, a defender, has captained Millwall's U18s and featured prominently in the U21s' recent nine-game unbeaten run.
