Baltimore Ravens quarterback Joe Flacco has been cleared from the concussion protocol and will play in Sunday's game against the Tennessee Titans, according to NFL Network's Ian Rapoport.
Flacco suffered the concussion after getting hit in the head by Miami Dolphins linebacker Kiko Alonso during Thursday's 40-0 win.
He returned to practice Wednesday.
Ryan Mallett took over for Flacco, going 3-of-7 for 20 yards and a touchdown against the Dolphins.
It's a great development for the Ravens, who are looking to close the gap on the division-leading Pittsburgh Steelers in the second half of the season.
