If convicted, Baker faces a mandatory minimum sentence of 10 years and up to life in state prison.
Baker's attorney, Bradford Cohen, blasted the decision to charge his client. In a statement, Cohen described it as "disgusting" and called for people to "go out and vote" for candidates who will reform the judicial system.
Both players have been on the exempt list since late July.
Baker and Dunbar were accused of robbery in May in their home state of Florida. Witnesses said Baker pointed a gun at attendees of a party and directed two other men, including Dunbar, to take their money and valuables.
Attorneys for each player maintained their clients' innocence, citing statements from witnesses.
Police reportedly obtained video footage and direct messages, however, that suggested a friend of Baker and Dunbar oversaw the payoff of the four alleged robbery victims.
Baker was a first-round pick in 2019, while Seattle recently acquired Dunbar in a trade with the Washington Football Team.
