Johnson dislocated a collarbone in the second half of Thursday’s 3-1 Europa League play-off victory over Amkar Perm and could be out for up to eight weeks.
“It was a good win against a difficult team but the game has been marred by the unbelievably blatant challenge on Andy Johnson,” said Hodgson.
“It has dislocated his collarbone and put him out for a long time.
“In these times when referees are supposed to be clamping down on challenges, you get a challenge like that which goes punished with a yellow card and we lose a player for eight weeks.
“I don’t think there’s any doubt the defender should have been sent off.
“If you commit blatant fouls that not only stop someone from going one on one with the keeper, but also put them in hospital, there’s a good chance you’ll get a red card.”
