Apparently did so on Saturday vs BC. This isn't the same knee he injured twice before but the other one. So both his knees are now injured. It's going to be tough for him to come back from this. I don't like the Riders but I hate seeing injuries like this. Rob is a class act & it is sad to see him go through another ACL tear. If Rob is smart, he'll think about the rest of his life & not the next time he can get on a football field for the Riders. Recovering from surgery & thinking about life after football should be his priorities now. I wish him all the best in his recovery.
