8:38 AM PT -- TMZ Sports has obtained the police report ... which says Woods is being accused of "tampering with evidence" because he allegedly put a lit joint in a water bottle.
Here's the deal ... cops say Woods was pulled over around 11:15 PM for going 77 in a 60.
During the stop, the officer smelled weed and believed Woods was stoned -- and asked if there was weed inside the vehicle.
Woods allegedly admitted to having a bunch of marijuana in the car. The officer says Woods had a backpack containing 2 mason jars of weed and a small gold cylinder of weed.
The officer says he noticed a half-empty water bottle with a joint floating in it -- and claims Woods admitted to putting it there while he was being pulled over. The officer says Wood was attempting to "get rid of potential evidence."
In total, cops say Woods had 2.07 oz of weed.
Dallas Cowboys defensive tackle Antwaun Woods was arrested in Texas for weed on Tuesday, law enforcement confirms.
The 26-year-old -- who started 8 games for the Cowboys in 2018 -- was busted in Frisco during a traffic stop where things clearly went south.
Woods is now facing multiple charges including possession of marijuana over 2 ounces but less than 4 ounces and tampering with evidence. He was also cited for possession of paraphernalia, as first reported by NFL Network's Ian Rapoport.
Woods was a stud defensive lineman at USC from 2012 to 2015 -- but didn't get selected in the 2016 NFL Draft.
Instead, he signed with the Tennessee Titans as an undrafted free agent -- and later signed a 2-year deal with the Cowboys in 2018.
So far, he only has 7 total tackles in 2019 with 0 sacks.
