[MLS] Defensive reinforcements have arrived for Toronto FC, whose pathetic back line coughed up three balls that New England turned into goals during a 4-1 rout on Saturday. Canadian Adrian Cann and Russian Maksim Usanov have joined the ranks, and much more is known about the former than the latter.

Cann, 29, comes back to MLS six years after playing a pair of games for Colorado, which drafted him No. 16 overall out of Louisville in 2004 yet released him in midseason. He returns from Danish club Esbjerg after playing for Montreal and Vancouver in the USL. A native of Thornhill, Ont., he is expected to either pair in central defense with, or replace, Nick Garcia, whose giveaways resulted in two of the Revs’ goals.

Usanov has played for clubs in Russia and Latvia. In Latvia, he played for Skonto Riga with Raivis Hscanovics, who suffered through a shocking MLS debut at left back against the Revs after being officially added to the roster just hours before kickoff. Usanov’s most recent foreign club was FC Krasnodar in a lower tier of Russian soccer.

Neither Cann nor Usanov can appear in an MLS game until their international transfer certificates are received by the league office. Usanov is also waiting on a work permit.

TFC, which has conceded six goals and scored one -- by Dwayne De Rosario against New England -- plays Philadelphia in its home opener at BMO Field on Thursday.
