Banks will undergo an MRI to confirm the severity of the injury, but the second-year tackle is likely looking at a 4-6 week absence if the MRI doesn’t reveal any additional damage. Banks has started all 19 games he has appeared in for the Saints since being drafted last year. He was replaced by fourth-year tackle Asim Richards in Sunday’s win over the Ravens, who allowed two pressures on the 15 pass-blocking snaps he was in on.
