TEMPE, Ariz. — Quarterback Carson Palmer of the Arizona Cardinals, 37, is coming back for a 15th NFL season.

“My intent was to take some time after the season to get away and see where I was physically and mentally,” Palmer said. “On both fronts I can say I’m ready to get back to work and prepare for the 2017 season.”

There had been speculation about Palmer and receiver Larry Fitzgerald for next season. Fitzgerald said last week he was returning. Palmer and Fitzgerald each agreed to one-year contract extensions last year. Palmer’s deal put him under contract through 2018.

Palmer had a superb 2015 season, throwing for 4,671 yards and 35 touchdowns with just 11 interceptions while leading the Cardinals to a 13-3 season.

But last year, both he and the team were disappointments.

Palmer threw for 4,233 yards – a sixth career 4,000-yard season – but only 26 touchdowns with 14 interceptions. The Cardinals, expected to be a Super Bowl contender, finished 7-8-1 for their first losing season in Bruce Arians’ four years as coach.

Palmer cited the returning talent in his statement.

“This is a phenomenal group with a very special opportunity in front of it,” Palmer said. “I know how rare that is and I couldn’t be more excited to be a part of it.”

COLTS: Indianapolis released 33-year-old linebacker D’Qwell Jackson, a move that will save the Colts about $5.5 million under the salary cap.

Jackson started all three seasons he was in Indianapolis, and was the defensive signal caller and leading tackler – before missing the final four games to serve a suspension for violating the league’s performance-enhancing substance policy.

SEAHAWKS: Seattle signed Blair Walsh, who spent five seasons in Minnesota before being released midway through last season.

Walsh is infamously remembered for missing a 27-yard field-goal attempt in the closing seconds of a 2015 NFC wild-card game against Seattle that could have given Minnesota the win.

Walsh was 12 of 16 on field goals and 15 of 19 on extra points last season before being released.

PANTHERS: The team president, Danny Morrison, resigned to pursue other career opportunities at the college level after serving as Carolina’s team president since 2009.
