TORONTO - Veteran defenders Adrian Cann and Ty Harden are among six players who won't be back with Toronto FC next season.

The Major League Soccer team announced Thursday that it had declined options on Cann and Harden, along with defender Dicoy Williams, midfielder Oscar Cordon, and forwards Nicholas Lindsay and Keith Makabuya.

Letting Cann, Williams and Harden go signals that the team was not happy with its defensive depth, hardly surprising in a team that allowed a franchise-worst 62 goals this season.

The moves are also likely not the first as TFC looks to revamp its roster after a disastrous season.

Cann, Williams and Lindsay all suffered long-term knees injuries, coming back at various times this season. Harden was sidelined most of the season with an abdominal injury.

Lindsay missed the better part of two seasons after wrecking his knee in a snowmoblie accident and only saw brief action at the end of the 2012 campaign.
