Embattled Minnesota Vikings running back Adrian Peterson allegedly admitted to marijuana use Wednesday during a court-ordered drug test, court documents said. Prosecutors in Montgomery County, Texas, claim the admission constitutes a violation of the terms of Peterson’s $15,000 bond in his child injury case and have asked a judge to order his arrest.

Peterson reportedly told an employee of the company administering his drug test that he “smoked a little weed” ahead of his exam and could potentially fail the screening, according to court documents obtained by TMZ Sports. Judge Kelly Case has yet to respond to the prosecution’s request and is unlikely to do so ahead of a scheduled recusal hearing.

Montgomery County District Attorney Brett Ligon filed a motion to recuse Case after the judge referred to him and Peterson’s defense attorney Rusty Hardin as “media whores,” KHOU reports. Initial reports said the recusal hearing would be held on Nov. 4, but Hardin said Wednesday that it would take place on Friday, the Minneapolis Star-Tribune reports.

Peterson’s trial on a felony charge of reckless or negligent injury to a child is tentatively scheduled to begin on Dec. 1. The Vikings placed him on the exempt/commissioner’s permission list in September, barring him from all team activities until his case is resolved.

The 29-year-old was formally indicted by a grand jury on Sept. 12 amid allegations that he beat his four-year-old son with a switch. If convicted, he faces up to two years in prison and a fine of up to $10,000.
