EDGE Analysis

The move saves the Cardinals $3 million against their salary cap, with the 35-year-old Redding -- who logged five tackles and a pick in 12 games in 2015 -- now a candidate to provide veteran defensive line depth elsewhere.

Redding has signed a two-year deal with the Cardinals that is worth $6 million, Kent Somers of the Arizona Republic reports. Per the Arizona Republic, Redding -- who recorded 35 tackles and 3.5 sacks for the Colts last season -- is in line to compete with Frostee Rucker for the Cards' defensive end role created by the departure of Darnell Dockett in free agency.

Redding had a sack and four total tackles in Sunday's win over the Bengals. Redding is on pace for a career high in sacks with three in seven games. He only has 15 tackles, but he's been a key component in a better-than-expected Indy pass rush without Robert Mathis.

Colts LE Cory Redding was forced from Indianpolis' Week 11 game against the Patriots with a hip injury, and will not return.

Colts LE Cory Redding (knee) has been ruled out for Week 7 against the Browns. The Indy defense is severely banged up. Also ruled out are DTs Fili Moala (knee) and Martin Tevaseu (ankle), OLB Robert Mathis (knee), and CB Darius Butler (shoulder). Inside linebacker Pat Angerer (foot) is listed as questionable. Trent Richardson could have a field day against the league's No. 29 rush defense.

Colts LE Cory Redding (knee) missed the entire second half of Sunday's loss to the Jets. Redding briefly returned after going down in the first quarter, but was gone for good after halftime. His presence was dearly missed as the Jets' previously moribund rushing attack rolled up 252 yards. It's good news Redding was able to play through the injury for even a few snaps, but his Week 7 status is very much up in the air.

Colts LE Cory Redding left Sunday's Week 6 game against the Jets with a right knee injury. Redding's return is questionable. The Colts' defense is getting absolutely gashed while playing without Robert Mathis, Redding and Pat Angerer.

Colts LE Cory Redding (knee) insisted he'll be ready for Week 1. Redding is rehabbing a mild MCL sprain. "I'm good, man," he said. "Fans don't need to worry. No. 90 will be on the field in Chicago." As one of the few Colts with 3-4 experience, Redding is a key part of setting the edge against the run.

Colts DE Cory Redding has been diagnosed with a "mild" MCL sprain, and could be out a "week or so." Redding will likely miss the Colts' final two preseason games, but should be ready for Week 1. Brought in to help anchor new coach Chuck Pagano's 3-4 defense, Redding is coming off a strong 2011, where he notched 43 tackles and 4.5 sacks despite playing just 511 snaps.
