BEREA -- Browns linebacker Chris Gocong suffered what appeared to be a ruptured right Achilles in practice this morning and is likely lost for the season.

Gocong will undergo an MRI today, but judging from the way Gocong grabbed the back of his leg -- the all-too-familiar "Achilles grab'' -- an Achilles is what is feared by Gocong and the team, sources said.

"It would be a huge hit,'' said linebacker D'Qwell Jackson. "Chris is a great player.''

Defending on a touchdown pass to tight end Jordan Cameron in the end zone, Gocong planted and then grabbed his lower leg, as if something in it had snapped. Gocong never left his feet, and it was a non-contact injury.

He then knelt for a moment, still grabbing his lower leg near the ankle. He succumbed to the obvious pain, laying on his back with his hands over his face and tapping his left leg.

Coach Pat Shurmur said the Browns are hoping it's nothing serious.

Gocong, the Browns' starting weakside linebacker -- and starting strongside for the first three games in the possible absence of Scott Fujita -- was helped onto the cart by trainers and couldn't put any weight on the right leg.

While on the cart, Fujita came over and patted him on the shoulder and said a few words. His teammates seemed to know it was serious.

It's the first major injury of camp. Browns punter Reggie Hodges suffered a ruptured Achilles in camp last year and missed the season. If it's an Achilles, it will likely require surgery.
