Zion Williamson's first NBA game didn't end the way he would have liked.

The first overall draft pick of the 2019 NBA Draft exited for good after the first half of the New Orleans Pelicans' Summer League game against the New York Knicks on Friday after suffering knee-to-knee contact.

On Saturday, the Pelicans announced that Williamson won't play during the rest of the Summer League in Las Vegas. Williamson has been diagnosed with a bruised left knee.

Although Williamson was removed from the game, the injury is reportedly not considered serious. The Pelicans will play their next Las Vegas Summer League game against the Washington Wizards on Saturday before concluding their schedule with two more games.

In the much-anticipated debut game between former Duke teammates, Williamson and RJ Barrett of the New York Knicks, Williamson scored 11 points on 4-of-9 shooting in nine minutes of playing time. However, he registered a team-worst -15 plus/minus rating on the stat sheet.

Considering the Pelicans have high hopes for their first overall pick in addition to the team's high ceiling with the additions of young stars in Brandon Ingram, Lonzo Ball and Josh Hart along with the veteran addition of J.J. Redick, there is no point in playing Williamson and risking further injury in a meaningless Summer League game.

We'll keep you updated regarding Williamson's injury, but the early prognosis is that it doesn't appear to be serious and he should be fine once the team begins training camp later this year.
