The Cardinals allowed the Titans to score 17 points in the final four minutes of regulation to force overtime, but a huge interception of Ryan Fitzpatrick in the extra period set up Feeley's winning kick.
Fitzpatrick hit Michael Preston for an eight-yard touchdown with just 14 seconds left in regulation to tie the game and cap a 17-point Titans run. Preston caught two touchdowns in the final four minutes of the fourth quarter as the Titans roared back from a 34-17 deficit.
After a 24-yard Rob Bironas field goal pulled Tennessee to within seven points with just under a minute left in regulation, the Titans were able to recover the ensuing onside kick. Fitzpatrick then moved the offense 54 yards in 37 seconds to tie the game.
Up 27-17 midway through the fourth quarter, Arizona seemed to have sealed the win when Antoine Cason jumped a pass by Fitzpatrick and returned it 20 yards for the pick-six.
The pick capped a 21-point run for Arizona, who trailed 17-13 midway through the third quarter.
The two teams alternated points through the first half as they battled to a 10-10 halftime draw. Rashard Mendenhall scored the game's first touchdown on a one-yard run late in the first quarter to put Arizona up 7-3. Chris Johnson answered for the Titans just before the quarter's end with a 25-yard catch-and-run.
After the Cardinals started the second half with a field goal, Tennessee took back the lead on their first possession of the third quarter. Four Arizona defensive penalties, two of which extended the drive on third downs, helped the Titans move 71 yards on 16 plays. Fitzpatrick found Delanie Walker on a one-yard touchdown pass to go up 17-13.
Then came the 21-point Cardinal run. Carson Palmer hit Jake Ballard for a six-yard score to take a 20-17 lead with two minutes remaining in the third quarter, then Mendenhall scored his second touchdown of the game from one-yard out midway through the fourth.
The Cardinals will likely need to win their remaining two games to make the playoffs. That won't be an easy task, as they'll face NFC West foes Seattle and San Francisco to close the season.
Fantasy studs and duds
The time share between Mendenhall and rookie Andre Ellington continued to frustrate fantasy owners. Ellington piled up 158 yards from scrimmage, but it was Mendenhall that got the goal line carries and scored two touchdowns. Larry Fitzgerald came within a half-yard of the endzone at one point, but finished with a relatively quiet six catches for 49 yards.
Chris Johnson scored an early touchdown but did little from that point on, finishing with 40 rushing yards and 51 receiving yards. Fitzpatrick put up big points, throwing for 402 yards, four touchdowns and two interceptions.
