Grizzlies Waive Matt Costello

The Grizzlies have officially waived Matt Costello, the team announced via press release. It’s unclear if Costello’s deal included any guaranteed salary that the team will be responsible for, as contract details have not been relayed for the initial signing.

Costello was waived by the Hawks last Monday and inked by the Grizzlies on Thursday. The undrafted rookie out of Michigan State averaged 4.0 points and 3.5 rebounds in 9.0 minutes during his two preseason appearances with Atlanta.

Memphis also confirmed the previously-reported release of Jordan Adams, so the team’s roster now stands at 15 players, which is the regular season maximum.
