McCoy completed 26 of 37 passes for 238 yards and a touchdown in Sunday's 27-17 win over the Rams.
In a battle of backup QBs with Kyler Murray (hamstring) and Matthew Stafford (concussion) both sidelined, McCoy came out on top over John Wolford with a solid performance that included a six-yard TD strike to fellow old-timer A.J. Green just before halftime. The 36-year-old Cardinal could return to the bench in Week 11 if Murray's ready to go, but if not McCoy would likely be under center for a tough NFC West battle against the 49ers. Although he picked up his own lower-body injury during the contest, McCoy suggested after the game he thinks it won't be an issue, Darren Urban of the Cardinals' official site reports.
