Andrew Ladd

Another Blackhawks winger, Andrew Ladd, confirmed that he was playing with a fractured left shoulder when he rejoined the lineup for the Blackhawks' last three games.

He said he injured it when he got caught in a weird spot with Patrick Marleau in game 4 against San Jose, but that the trainers kept him from feeling too much pain
