Grizzlies' Matt Costello: Signs contract with Grizzlies

Costello signed a contract Thursday with the Grizzlies.

Analysis:

Costello went undrafted in June after a four-year college career at Michigan State, but was able to land a partially-guaranteed contract from the Hawks that included an invite to training camp. He was waived by the Hawks earlier this week, but the Grizzlies want to get a quick look at him prior to the regular season. Costello is not a candidate to make the 15-man roster and is likely just getting an audition for the Iowa Energy, the Grizzlies' D-League affiliate.
