Collins' car crashed into a tree in Owings Mills around 6:48 a.m., according to police. The charges against Collins are expected to be announced Friday afternoon.
Collins, 24, ranked 11th in the NFL in rushing in 2017 with 973 yards and drew national attention for his Irish dance moves. Last season, he struggled with a foot injury and a lack of explosiveness, losing the starting job to undrafted rookie Gus Edwards and spending the final five games on injured reserve.
There were no guarantees that Collins would return to the Ravens even before his arrest, as he was a restricted free agent whom the team might not have tendered.
