Ah, loopholes! Michael Vick might be eligible for a 50-percent discount on his 23-month prison sentence. All he has to do is join a drug rehab program.

Under the program, Vick could be released after serving only 12 months of the 23-month sentence he was given Dec. 10 in Richmond, Va. His exact release date remains fuzzy, as it is unclear whether the 12-month stretch would be counted from the day he entered Leavenworth or the day he voluntary entered prison in November.

Two sources tell Yahoo! Sports that Vick qualified for the drug program because his 23-month sentence included his failed drug test for marijuana after pleading guilty to the dog fighting charges.

I've never known someone to need rehab for weed, but if he's eligible, he's eligible.
