PDB was quoted as saying something along the lines of "If [Larsson] hadn't already played 30+ games in Albany he'd probably be sent down".
And I'm pretty sure Larsson also said something like he'd rather stay and practice with the big squad and the coaches.
You don't make a roster change when the team is winning. After the team loses I expect Larsson to be put in.
I expect him to be put in Saturday, win or lose.
