Rapp (concussion) was a full participant during Friday's practice and doesn't currently carry an injury designation heading into Super Bowl week, Brady Henderson of ESPN.com reports.
Rapp, who has missed the entirety of the playoffs while out with a concussion, appears to be on track to play in the Super Bowl. It's unclear how the free safety will figure into the defense, as veteran Eric Weddle has done an excellent job filling in for him over the Rams' three previous postseason wins.
