Former Tokyo Apache center Jeremy Tyler's stint with the Atlanta Hawks lasted one game — a total of five minutes.

The Hawks released the 21-year-old center on Wednesday, the day they signed guard Shelvin Mack to a 10-day contract.

Now, his future in the NBA is a question mark.

"Jeremy simply must grow up and learn to be a better teammate," former Apache and NBA bench boss Bob Hill told The Japan Times on Saturday. "It's very difficult to establish yourself if maturity is an issue. It will be interesting to see now what his agents do with him."

Atlanta coach Larry Drew said the team needed to shore up its backcourt depth. Guard Lou Williams sustained a torn anterior cruciate ligament (ACL) and was lost for the season in January, and ex-Wake Forest guard Jeff Teague suffered a sprained left ankle earlier this week.

Mack, who attended Butler University, averaged 20.1 points per game (third-highest output) and 7.7 assists (No. 2) in 23 games for the NBA Development League's Maine Red Claws. He played in 64 games for the Washington Wizards last season.

After being traded to the Hawks on Feb. 21 in a salary-dump move by the Golden State Warriors, Tyler's only time off the bench came on Monday against the Denver Nuggets, and he finished with three rebounds.

Tyler played for the Apache, one of the bj-league's first six clubs, in the 2010-11 season. The bj-league team folded after that season.
