Pierce's 2014 Ford Mustang was stopped just before 2 a.m. for speeding at Dulaney Valley Road and I-695 in Towson, Maryland, the Baltimore County Police Department said in a report obtained by NFL Media.
After failing field sobriety tests, Pierce was arrested and taken to the Towson precinct for processing.
The 23-year-old Pierce was processed and released from custody.
"Do you know what happened the last time a Ravens player got a DUI?" Pierce asked the officer while en-route to the station. "I'm getting cut tomorrow, not like you care."
Prior the Ravens releasing Pierce on Wednesday, we viewed the back as a likely candidate to be cut before the beginning of the season.
After starting the first two games, Pierce suffered through another terrible campaign in 2014. Beset by an early injury, he earned just 366 yards on 93 attempts -- a 3.9 yard average -- and scored just twice. He owns a career average of 3.8 yards per carry and isn't a short-yardage battering ram -- five career touchdowns. Now with the legal situation hanging over his head, Pierce won't find many suitors on the open market.
