Earlier this month, Essendon signed new two-year contracts with Leroy Jetta and Henry Slattery and offered a one-year contract extension to 2007 recruit David Myers.
Those three players are now also contracted until the end of the 2010 season.
“These three young men are emerging players and we expect them to play key roles for a long at time be part of an exciting new era for Essendon.”
Knights said the four most recent contracts are an especially good sign for the club as they are for interstate players from WA (Myers, Jetta, Gumbleton) and SA (Slattery).
