Cardinals' Matt Prater: Stays limited in practice

Prater (knee) practiced in a limited fashion Wednesday, Josh Weinfuss of ESPN.com reports.

Prater now has been listed as a limited participant on five consecutive injury reports dating back to last Wednesday, but it's unclear if he needs to get back to full participation in order for the Cardinals to feel comfortable enough for him to resume kicking for the first time since undergoing meniscus surgery on his left knee in October. Arizona will need to activate him from injured reserve by 4 p.m. ET on Saturday in order for him to play later that evening versus the Rams, but if he doesn't get back on the active roster for that contest, Chad Ryland will continue to handle placekicking duties for the Cardinals.
