“Post game he may have been a little bit groggy - it was a pretty big hit,” Knights said.
“I thought Matthew and Chris probably came off the hit nearly as bad as each other.
“It was a significant meeting head on so Matthew got up and played a really consistent game when he got back to his feet and he’s going to be right to go.
“He will train and lead the club on Sunday.”
In a wide ranging interview, Knights rated Fremantle are a dangerous side and also revealed Essendon has not discussed the possibility of drafting Ben Cousins.
“No we haven’t discussed it at all. It hasn’t even crossed our list management discussion what-so-ever,” he said.
“We are bringing a young group together, that is out vision but we haven’t discussed Ben Cousins.”

Knights also admitted the season ending back injury to Jason Winderlich is frustrating.
“It’s been a stop start year for Jason and he is a very important player for our club so it is disappointing to have him out for the entire season,” he said.
“It got to the stage that he needed an operation to be cured and get back to his best. He’s a pretty resilient sort of character so he will get through it.”
