Gonzaga freshman Zach Collins will enter and remain in the NBA Draft, a source confirmed to CBS Sports.

A formal announcement is expected soon.

Collins averaged 10.0 points and 5.9 rebounds in 17.2 minutes while helping the Zags win 37 times and advance to the title game of the 2017 NCAA Tournament, where they lost to North Carolina. The 7-foot forward got 14 points, 13 rebounds and six blocks in Gonzaga’s national semifinal win over South Carolina. He is the first one-and-done player in Gonzaga history.
