Gordon, 34, was a late withdrawal from the round 22 side which lost by one-point against the Panthers last Saturday.
The fullback suffered a dislocated wrist in the clubs final contact session leading up the game, where he was forced to go to hospital to have it put back in under some general anaesthesia.
Catterick told titans.com.au he was in a bit of pain at first but it’s all over with now.
“We’re taking it as a week to week proposition, he’s in a sling for two weeks,” Catterick said.
“Haven’t ruled him out for the season just yet, but he’ll do everything he can to try and play the last game.
“They definitely weren’t talking to each other when he came off the field and the surgeon had to force his way to make them reunite.”
Catterick also explained that if Gordon was to return this season, he might be able to play with a brace, but it could restrict what he does within a game.
“The ligament repair is the big issue now, the bones are back in place and it’s just that ligament repair. Its a pain tolerance thing once the swelling goes down,” Catterick said.
Brenko Lee was another late withdrawal, as he suffered from a hamstring injury.
Lee, 22, has played all games for the Titans since Round 10 this season, and has been named for this weekend’s clash against the Sea Eagles.
Catterick said Lee has had a history of hamstring injuries so it was just a precaution he didn’t play.
“We’ve got three more games left now, we really need Brenko in our side to compete in the last three games,” Catterick said.
“He ran fine. He ran a kilometre than participated in the team session, so looking good for the weekend”.
