RICHMOND -- Multiple sources close to the Michael Vick case told WSB-TV Channel 2 Friday they are skeptical of reports that Vick will not admit killing dogs or gambling on dogfights during his plea hearing on Monday.

ESPN reports the Atlanta Falcons quarterback will plead guilty only to the charge of interstate commerce for the purpose of dogfighting.

Channel 2’s sources, who know the judge in this case, said the plea deal could unravel if Vick doesn't admit what his co-defendants already have sworn in court – that he gambled and killed dogs.

Vick will have to sign a “summary of facts” that is basically a confession. ESPN’s source said Vick is balking at signing the agreement, maintaining he never killed dogs or gambled.

If Vick’s story doesn’t match his co-defendants’ Judge Henry E. Hudson could object to the plea deal or hammer Vick with a very stiff sentence.

The judge is not bound by any sentencing guidelines.

Vick’s three co-defendants all signed statements saying Vick funded the dogfighting operation, gambled on fights and executed eight dogs at his Virginia property when they performed poorly.

Attorneys familiar with Judge Hudson told Channel 2 Action News that he will question the plea deal if Vick tries to “downplay his involvement.”

“The problem with Vick is that he was not just some casual dog fighter,” said Jonathan Turley, George Washington University legal analyst.

“He appears to have been heavily invested in this type of crime. It's hard to imagine he didn't know it was illegal. And it's certainly hard to believe he didn't know how cruel it was"

Vick faces up to five years in prison and the possible end of his football career.
