"A toe injury has prompted the Mavericks to scrap their agreement to sign Devin Harris to a three-year, $9MM deal, tweets Marc Stein of ESPN.com. Dallas remains interested in signing him, but the surgery required is expected to keep Harris out until the start of the regular season, according to Stein (Twitter link). First-round pick and fellow point guard Shane Larkin suffered a broken ankle in summer league practice, as Adrian Wojnarowski of Yahoo! Sports notes via Twitter, so it's possible the pair of injuries prompted the Mavs to call off their plans with Harris."
That's 2 down for Dallas.
