Prater (knee) was a limited participant in Wednesday's practice, Josh Weinfuss of ESPN.com reports.
Prater made his return to practice after the Cardinals designated him for return from injured reserve Wednesday. After missing the Cardinals' last 10 games, Prater may need to upgrade to full participation in practice by the end of the week for Arizona to feel comfortable activating him from IR ahead of Sunday's matchup with the Panthers. If Prater ends up missing another game, Chad Ryland should continue serving as Arizona's kicker.
