OJ Simpson is expected to find out next week whether his prison sentence for trying to take sports memorabilia will be cut. 

He was before the Nevada Board of Parole Commissioners on Thursday asking for leniency and expressing his regret over his actions.

Simpson, 66, was dressed in blue prison clothes as he appeared before the board via closed-circuit television from prison.  

"I just wish I never went to that room," he told the seven-member parole board. 

Simpson said he missed his kids and expressed regret at missing important family events, like their college graduations and the funeral of his sister.

"I missed all the birthdays," he said.  

Whether his good behaviour behind bars for the last five years will count in his favour is not certain. 

Parole Commissioner Susan Jackson and hearing representative Robin Bates will make a decision on his release some time next week.  

Even if the parole board's decision is positive, there are reports that the former footballer will still not be free because sentences related to other charges.

Simpson was sentenced to up to 33 years in prison following his 2008 conviction on kidnapping, armed robbery and other charges.
