The decorated AFL career of Chris Judd could well be over after the Carlton superstar suffered a serious knee injury early in Saturday’s clash against Adelaide.

Judd, 31, was stretchered from the MCG during the first quarter, with scans later confirming he had ruptured the anterior cruciate ligament in his left knee.

Caretaker coach John Barker paid tribute to the impact Judd has had on the club, but was reluctant to be drawn on his future.

“I don’t think we probably need or want to be too rash with the decisions we make about Chris at the moment,” Barker said after the nine-point loss to the Crows.

“He’s a champion of the game and he’s been massive for this club.

“What do you say? My heart goes out to him and our club’s heart goes out to him.

“It’s disappointing.”

Judd landed heavily on his left leg in a marking contest with Crows star Patrick Dangerfield and immediately collapsed to the turf in pain.

The dual Brownlow medallist started to limp towards the bench from the outer wing with the help of trainers but play was stopped so he could depart the arena on the motorised cart.

He was immediately subbed out of the game, with Jason Tutt taking his place.

Judd contemplated retirement at the end of the 2014 campaign before signing on for one more year.
