Connor Watson

Just days after Watson celebrated his 100th NRL appearance, the Knights announced on Tuesday that Watson had accepted a deal elsewhere and would leave after four seasons in the Hunter.

There has been no official statement on Watson's next move, but NRL.com understands the Roosters are leading the race to secure his signature.

The 27-year-old hadn't missed a game in nearly two years but was forced to sit out the Roosters' fourth-straight win after he copped a knock to the mouth in the final minute of the Round 3 clash against the Panthers.

"I got hit with something – an elbow or something – and it pushed my three front teeth in," he said on Monday morning.

"I went and got them pulled back and now I've got a wire holding them in place. The dentist said that should keep them there and hopefully I don't get a whack and lose my front teeth.

20 year-old Watson expressed his delight at extending his contract with the Tricolours.

"I'm very excited to extend my time with the Roosters," said Watson.

"I'm learning so much from Robbo (head coach Trent Robinson) and the coaches, and this is where I want to build a career. 

"I know I still have a lot of improvement in me, and hopefully I'll keep learning and improving and secure an opportunity to play some good footy for the Roosters," he added.

Robinson said it was exciting to have Watson extend his arrangement with the club.
