TORONTO -- It looks like Toronto FC will get a boost on defence Sunday with the return of captain Steven Caldwell.

The Scottish veteran has missed 13 games through injury or suspension this season, most recently with a quad muscle problem.

But the centre back is expected back for Toronto (9-11-7) on Sunday when struggling Chivas USA (6-16-6) comes to BMO Field.

Midfielder Jonathan Osorio (hamstring) is also expected back Sunday. Midfielder Collen Warner (hamstring) and defender-midfielder Bradley Orr (toe) are not available.

Both teams have been on poor runs of late. Chivas is winless in 10 (0-9-1) while Toronto (0-4-2) is winless in six.

A loss to Toronto, coupled with a Vancouver win over Portland later today and Chivas will be eliminated from playoff contention.
