Ipswich boss Paul Jewell felt it was the right decision to abandon his side's pre-season friendly against Colchester after 78 minutes.
The game was called off when Us midfielder Andy Bond suffered a serious head injury in a collision with team-mate Mark Cousins.
Bond, 25, eventually walked off the pitch after receiving lengthy treatment but was still taken to hospital in an ambulance.
"The lad was in a bad way and his well-being is the main thing. The referee said it was pretty serious so it was the right call," Jewell told the club's official website.
Colchester manager John Ward added: "The referee made the correct decision in saying we don't need to continue. The decision was agreed by Paul Jewell and myself.
"It could have been a lot worse, he's had a bit of concussion, he's lost a tooth and there's cuts around his face. He was totally disorientated, and in a very bad way."
