Federal prosecutors asked a judge Tuesday to order Michael Vick to set aside nearly $1 million for the care of pit bulls seized from his dogfighting operation.

In court papers filed Tuesday, the government noted what they called Vick's "deteriorating financial condition" in asking a federal judge in Richmond to issue a restraining order that essentially would freeze about $928,000. That would pay to care for the dogs and find homes for them.

Vick faces up to five years in prison when he is sentenced December 10 on a federal dogfighting conspiracy conviction. He voluntarily began serving his prison term Monday.

As part of his plea deal, Vick agreed to make restitution for the care and placement of the 54 pit bulls confiscated from his "Bad Newz Kennels" property in Surry County.

Prosecutors say claims and lawsuits by Vick's creditors and his former employer, the Atlanta Falcons, threaten his ability to make good on the agreement.

Vick's lead attorney, Billy Martin, did not immediately respond to telephone and e-mail messages seeking comment.
