Lions Football Manager David Noble said the club was disappointed the footage went to air.
"It was just a knock on his AC, having a jab is not unusual in that injury because it is a relatively safe option," Noble said.
"He got it in the second quarter, played all the way through, but got another knock on it in the last quarter, he wanted to play on so we decided to give him some pain relief.
"It was in the race to our rooms, the doctor thought it was an appropriate spot to have an injection and I haven't heard from the AFL at this point in time.
"We were just unlucky there was a camera down there and we were disappointed when it got broadcast to the public."
