The Miami Heat are releasing guard Andre Dawkins before his contract becomes fully guaranteed Wednesday, a league source told RealGM.

Dawkins, a 6-foot-4 sharpshooter out of Duke, notched three points and 21 minutes played over four appearances with the Heat this season.

Dawkins made the regular season roster out of training camp, intriguing Miami with his shooting. He spent most of his game action with Sioux Falls in the NBA D-League, averaging 23.5 points and 52 percent three-point shooting.

Dawkins, 23, went undrafted last June after playing four seasons at Duke, but was one of the draft’s best shooters and played significant roles in summer league for the Heat and Houston Rockets.
