EARTH CITY, Mo. -- The St. Louis Rams officially put safety T.J. McDonald on injured reserve Friday, ending his season. McDonald is set to have shoulder surgery in the coming weeks.
Maurice Alexander is expected to start in McDonald's place. The Rams promoted cornerback Eric Patterson from the practice squad to take McDonald's spot on the roster.
Elsewhere on Friday's injury report, the Rams look like they'll be without cornerback Janoris Jenkins against Detroit on Sunday as he goes through the concussion protocol.
