Keenum (concussion) is active for Sunday's game against the Cardinals, Jim Thomas of the St. Louis Post-Dispatch reports.
Keenum has managed to achieve passage through the concussion protocol, but his inability to practice beyond a limited capacity this week spurred head coach Jeff Fisher to name Nick Foles the Rams' starting quarterback for the second consecutive contest. However, Keenum will serve as the No. 2 signal caller Sunday in anticipation of a return to the starting role next Sunday versus the Lions.
