Concussion was the main topic of last weekend's rugby, specifically the decision to allow Australia's Nic White back on the field after a series of head bangs and a wobbly time on his feet.
A heated debate ensued in the Virgin Sport studios between Matt Williams, Joe Molloy, and Rob Kearney, with Williams coming in for a lot of criticism after siding with the doctors who allowed White to continue.
During his regular rugby chat with Balls - in association with Ladbrokes - Stephen Ferris, who was coached at Ulster by Matt Williams, gave his opinion, in no uncertain terms, on the matter.
Always put yourself in the position of the player, and obviously I’m very able to do that because I played at the highest level. Matt Williams hasn’t.
For him to turn around and tell us all to trust science, and we should put our faith in the medical doctors making these decisions. At the end of the day they got it wrong.
"Nic White has now been stood down from Australia duties, that underlines once more that they got it wrong.
"This has been talked about all week. He got up, he stumbled, he went down on one knee, glassy eyed, he looked dazed, they’re all signs and symptoms of concussion.
"You don’t need to do a degree in whatever science that he has studies to make a judgement on somebody if they’ve got concussion or not."

"It’s not the independent doctor here who is at fault," continued Ferris. "The independent doctor was probably on his way to do the HIA with Nic White at the time. He mightn’t of been able to see all the replays on the TV.
"But the people who were able to see all of those were the Australian medical staff, they’re the ones who are treating him on the pitch. They should be the ones answering the questions. They should be taking the flak for any misjudgement.
"This does not set a good example for women, men, kids, who are sending their children to mini rugby. These things cannot be happening week in week out at the highest level.
"Because if it’s happening at the higher levels, how’s it going to be at the lower levels."
