Paul Kent has revealed that Mitchell Pearce's thumb injury may not have been suffered at training after all.

Speaking on Fox Sports' NRL 360, Kent said there may be a more sinister event behind the injury.

Pearce underwent surgery at the start of the year and the Knights said it was due to a training injury.

Kent said that there were rumours circulating that the incident had occurred in a "street fight" rather then at training.

Newcastle coach Adam O'Brien however denied the report according to Kent.

โ€œI asked Adam Oโ€™Brien about that some weeks back whether it was true or not. He categorically denied it, he said it happened in a tackling drill so you accept that.โ€

Pearce signed a one-year extension to stay at Newcastle on Tuesday, with O'Brien saying at the time that Pearce ย โ€œhas never been violent... Yes, he has hurt people close to him but heโ€™s never had to front up for being violent.โ€

Kent believes the peculiar statement may have been O'Brien getting on the front foot of the rumours.

โ€œThere was a rumour that the broken thumb that he suffered at training came from a street fight,โ€ Kent said.

Journalist Paul Crawley said the comments were more than just odd.

โ€œThatโ€™s an absurd comment for Adam Oโ€™Brien to make,โ€ Crawley said.

โ€œI know heโ€™s trying to protect his player, but you sacked him as captain. You made that call, you made a decision.

โ€œHe let the team down so youโ€™ve taken the captaincy off him and now youโ€™re saying the critics are coming for him.โ€

Pearce has been no stranger to scandals during his career and even during his time at the Knights.

Recently he was forced to call-off his wedding due to a texting scandal regarding a female employee of the club.

Newcastle will get their 2021 season underway against Canterbury on Friday at McDonald Jones Stadium.
