Bryant was booked into a Miami-Dade County, Fla., jail at 9:24 a.m. ET and was being held on a bond between $200 and $1,000.
"We're aware of the situation and are gathering more information," Raiders spokesman Zak Gilbert said in a statement.
It's never a good time to get arrested, but Bryant's slip-up is especially poorly timed. The 6-foot-5 veteran is entering unrestricted free agency for the first time in a few weeks. He was seen as one of the more talented defensive linemen on the market and was in line for a solid contract. This will complicate matters.
