We are going to use practice jerseys for an upcoming tournament. Unfortunately, our practice jersey numbers don't match our regular game jersey numbers!? Is there a way to do this so that the player stats carry over for this tourney and regular season games for each player? Can I change the player numbers after the tourney?? Any advice would be greatly appreciated!!

You can change the jersey numbers in the lineup for a game, and the player's stats are still recorded with the "underlying" player. The jersey number is just a piece of information, and can be changed in the lineup from game to game with no stat issues.
