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 last 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.

Salary issues were also likely a concern. Cann, a former TFC player of the year who later held out over a contract battle, made US$134,750 last season. Harden made $98,666.

Williams, a Jamaican international, made $53,500 while the other two were at the minimum of $44,000.

Like Lindsay, Cordon and Makubuya were Toronto FC Academy products.

The 32-year-old Cann made 65 appearances during his three seasons with Toronto FC. He signed with the club on April 12, 2010 as a free agent after leaving Esbjerg FB of Denmark. He has also earned nine international caps for Canada.

The 28-year-old Harden, acquired in a trade with Colorado in 2010, made 58 appearances with the club.

Williams, 26, made 13 appearances during two seasons.

Lindsay, 20, signed with the first team in 2010 as the second Academy graduate in club history and made six appearances in his first season with the club.

Cordon and Makubuya, both 19, signed with the first team on March 17, 2011 after graduating from the Academy. Cordon made six appearances in two seasons, while Makubuya made two substitute appearances over two seasons.
