Draymond Green is expected to receive some form of disciplinary action after striking Jordan Poole during a Golden State Warriors practice, sources told Chris Haynes of Yahoo! Sports.

Green and Poole reportedly had prior history, though no Warriors players felt that Green's actions were warranted.

Green was apologetic following the incident. 

Teammates noticed a change in Poole's behavior during training camp as he closed in on a new contract, according to sources.
