Toews returns for 2nd period after big hit

In a physical first period, the Blackhawks might have got the worst of it when Jonathan Toews was forced off the ice after a hit from the Blues' David Backes with about three minutes left in the period.

Backes appeared to hit Toews around his right knee. Toews was limping as he left the ice and went to the locker room.

Toews returned to take the opening face-off of the second period.
