'Smallville' Actor Sam Jones Checks Into Prison

Former "Smallville" actor Sam Jones just moved into his new home for the next year -- federal prison.

Jones checked in to the low-security correctional facility in Lompoc, California some time this week -- beginning his 366-day sentence for the role he played in a massive drug ring.

As we previously reported, Jones pled "guilty" to conspiracy to sell more than 10,000 Oxycodone pills ... and was sentenced in June.
