9:10 AM PT -- According to a police report, obtained by TMZ Sports, cops were called to Holyfield's dorm after an RA smelled weed coming from his room.

Cops say Holyfield answered the door and had bloodshot eyes. He said he hadn't been smoking and didn't know what they were talking about, despite a strong smell of marijuana.

According to the report, police had to get a search warrant because Holyfield wouldn't let them into his room. Once they got in, they saw a window had been opened. An officer checked the ground outside the window and found "seven buds of suspected unburned marijuana."

Cops say they also found a glass pipe inside an iPhone case covered in marijuana residue.
