SALT LAKE CITY — Adam Morrison and Sasha Vujacic had a heated confrontation late in practice today. Morrison was upset that Vujacic was holding him during a 4-on-4 game. No punches were thrown, but the players were clearly unhappy with each other. Stuff like this goes on all the time during NBA practices, but it’s rare that it happens after reporters are allowed into the gym at the end of a workout. It’s also the main reason reporters aren’t allowed into the gym to watch until the end of practice. At any rate, none of the Lakers players or coaches seemed concerned that things would escalate between Morrison and Vujacic. Neither is known for his temper.
