I was at the Blues game on sat. so I did not have any commentators input.    In the third period, after Nolan and a Blues player recieved offsetting roughing penalties,  Andrew Brunette skated over to penalty box and sat with Nolan for the duration of the penalty.  The friend that was at the game with me and I assumed that Nolan had recieved a ten minute misconduct on top of the roughing, but was out at the end of the two minutes.  Did they mention this on the broadcasts or did anyone else at the game notice this.  Is it legal to voluntarily send a player  to the box to sit and stratigize with. a penalized player.  I have never seen or heard of this before.  Any input would be great.
