TUESDAY 5:06pm: The Heat have offically announced Hamilton's signing in a press release. The release also includes confirmation that Miami has signed Eric Griffin whose agreement with the team was reported nearly a month ago. SUNDAY 11:28am: The Heat will bring Justin Hamilton to training camp agent J.R. Hensley tells Barry Jackson of the Miami Herald. Hensley says his client who's been working out at the Heat's home arena the past few weeks will ink a deal with the team in the days ahead. The 45th pick in the 2012 draft still isn't participating in any contact drills as he recovers from a hamstring injury that kept him out of summer league. The signing will force Miami's brass to either keep the former LSU center into the regular season or cut him in training camp and lose his rights. The Heat could keep Hamilton's NBA rights in perpetuity if they elect not to sign him as they did last year when he played in Europe. With some agents hearing that the Heat plan to carry only the minimum 13 players amid a luxury tax crunch this season it's somewhat surprising that the team appears to be bringing Hamilton aboard now. Miami already has 13 fully guaranteed contracts.
