The school has not made an official announcement on Blackmon's status with the team.
"Rules are rules.. Abide by them or suffer the consequences.... Looking forward to the Texas game," Blackmon said on his Twitter account.
“Yea, We have team standards, and there's consequences if you don't follow them, I shouldn't wear earrings But I'll bounce back,”
Blackmon’s tweets regarding the violation were soon deleted.
Head coach Bronco Mendenhall refused to discuss the details of Blackmon's status.
"Any of the matters with our team discipline-wise will be internal,” Mendenhall said after practice Tuesday. "It seems like this generation likes to have press conferences through selfies. I'm not going to do that."
According to the BYU honor code, wearing earrings and other body piercing are not acceptable.
Running back Jamaal Williams will also miss the Connecticut game after being being arrested in March on a misdemeanor charge of underage drinking.
