The Minnesota Vikings are going to back up Michael Floyd's kombucha tea defense.

Floyd is due in court Monday after reportedly failing an alcohol test three days before his house arrest was set to end. After initially proclaiming reports of a failed test as "totally false," Floyd released a statement confirming that he did in fact fail the test for any traces of alcohol. He stated that "he drank several bottles of kombucha tea drinks, unaware that the drinks contain alcohol," as an explanation.

When he heads to court on Monday, he'll have the team backing up his assertion, according to the Pioneer Press.

Vikings chief operating officer Kevin Warren wrote a letter to Floyd's attorney, Robert Feinberg, who attached it to a defense motion urging Scottsdale City Judge Statia Hendrix to cancel the hearing and reinstate electronic monitoring for the last five days of Floyd's 96-day home confinement. Warren corroborates Floyd's claim that he was unaware kombucha tea contained alcohol when he drank several bottles while watching movies late into the early morning of June 11 at the Minnesota house of Vikings tight end Kyle Rudolph, his former college roommate at Notre Dame.

Floyd's affidavit states that he drank "four or five bottles" of kombucha tea while watching movies late into the night.

"After falling asleep, I awoke to the beeping of the home-monitoring machine, signaling that I must complete a test," Floyd said. "I had several sips of kombucha right after waking up, just before blowing into the home-monitoring testing machine. I had not eaten anything since noon on June 10.

"I received a call on June 12 from an administrator at Sentinel Advantage, informing me of the results of the three tests from the morning of June 11 and informing me that I missed a fourth test. Until I was contacted by the administrator at Sentinel Advantage about the report related to the morning of June 11, I had no knowledge that kombucha contained alcohol, or that some types of kombucha have a higher alcohol content than others."

Floyd was under house arrest and subject to alcohol tests as a result of the punishment stemming from his arrest on charges of extreme DUI late last year. Floyd was found asleep at the wheel of his car at a traffic light last December, and later was charged with two counts of DUI, one count of obstructing a roadway and one count of failure to obey a police officer. He was released by the Cardinals soon after the arrest, and then picked up by the Patriots. He spent the postseason on New England's roster but did not play in the Super Bowl LI victory.

In February, Floyd was found guilty of extreme DUI and sentenced to 24 days in jail and 96 days of house arrest. He was less than a week from completing the period of that house arrest when he failed those tests. He signed with the Vikings in early May.
