The Hawks will formally introduce three free agents, all of whom previously agreed to deals with the team, on Wednesday.
The team will sign guards Quinn Cook and Josh Magette and forward Tyler Cavanaugh.
Cook agreed to a partially guaranteed two-year deal with the team. He will attend training camp later this month and is expected to compete for a third point guard position.
Magette will sign a two-way deal and will play for the Erie BayHawks of the NBA G League. He can be with the Hawks for a maximum of 45 days under the contract.
Cavanaugh will sign a partially guaranteed rookie contract and will attend training camp.
