Police said 21-year-old Ludgero Rodrigues was cited Thursday for failing to stop at a red light.
A police report says Rodrigues was driving a Mercury Villager minivan and struck Brady's Audi sedan at an intersection in Boston's Back Bay area near Brady's home. A 49-year-old passenger in the minivan was seriously injured. Brady was not hurt.
The report says Brady told officers he had a green light on Gloucester Street and attempted to swerve out of the way when the van crossed his path. His car struck the passenger side of the van.
Brady took part in the team's practice Thursday.
A telephone listing for Rodriques could not immediately be found.
