Aberdeen's Rob Milsom thinks Steven Naismith should have seen red for a high tackle prior to suffering knee ligament damage.
The Dons midfielder was caught by the Rangers forward in last Saturday's game at Pittodrie, but it was not until five minutes later that Naismith collapsed as his knee gave way as a result of the earlier challenge.
Naismith is now set to miss the remainder of the season, although Milsom was surprised that referee Willie Collum did not take action at the time.
Milsom has dismissed the notion that Naismith intended to cause any harm and he now hopes the 25-year-old returns to action as soon as possible.
"It was quite a high tackle from Stevie and it should have been red," Milsom told the Daily Record.
"It was a sore one for me and there was quite a gash on my leg, but the medical team covered it up.
"I was lucky my standing foot wasn't planted on the floor otherwise I could have been seriously injured.
"But I know Naismith isn't a malicious player and he came off worse.
"I wouldn't wish that injury on anyone. I hope he's back playing as soon as possible and I wish him the best."
