The Hawks will fill one of their two open roster spots this week by signing shooting guard Antonius Cleveland to a 10-day contract, sources tell Shams Charania of Yahoo Sports (Twitter link). Cleveland, 24, went undrafted out of Southeast Missouri State, but played for the Blazers in Summer League and then signed a training camp deal with the Warriors last summer. While he didn’t earn a spot on Golden State’s regular season roster, he later caught on with the Mavericks, signing a two-way contract with Dallas and appearing in 13 games for the club. He was waived by the Mavs in December.
