The St. Louis Rams activated cornerback Marquis Johnson from the PUP list today. To free up space for Johnson, the Rams moved cornerback Brian Jackson to injured reserve. Johnson had offseason knee surgery that kept him out of training camp this year. Johnson joins a cornerback group hit hard by injuries, including season enders to starters Ron Bartell and Bradley Fletcher. Brian Jackson, a second-year player most recently with the Giants, was added earlier this month, taking Bradley Fletcher's spot on the roster and is the fourth Rams cornerback to end his season on the injured reserve list so far this year.
