TUESDAY, 12:50pm: The Cardinals have placed Mathieu on the injured reserve list, officially ending his season. As expected, the club has added a safety to the 53-man roster to provide some depth, re-signing veteran free agent Chris Clemons, who was cut by Arizona from IR earlier this season (Twitter link link via Urban).

MONDAY, 1:26pm: The Cardinals clinched the NFC West with their victory Sunday night over the Eagles, but that win came at a cost. Head coach Bruce Arians announced today that standout defensive back Tyrann Mathieu will miss the rest of the 2015 season – and postseason – after suffering a torn ACL (Twitter link via Darren Urban of AZCardinals.com).

Mathieu, 23, started all 14 games for the Cardinals this season, spending time at both cornerback and safety. Having already established new career highs in tackles (89), interceptions (5), and passes defended (16), the former third-round pick was one of the key players on defense for Arizona, so his loss will be a crushing one for the team.

Pro Football Focus had Mathieu ranked as the top cornerback in the NFL this season, grading him as the best in the league both in coverage and against the run. Defensive coordinator James Bettcher recently told Albert Breer of the NFL Network that he believed Mathieu should receive consideration for the league’s defensive player of the year award.

The Cardinals were also without Rashad Johnson during Sunday’s win over Philadelphia, so it wouldn’t be a surprise to see the club add another safety to the 53-man roster this week — Tony Jefferson and D.J. Swearinger could see increased roles, with Mathieu headed to IR.

As anticipated, Giants wideout Odell Beckham Jr. is appealing his one-game suspension, and that appeal is scheduled for Wednesday, with James Thrash serving as the hearing officer, tweets Chris Mortensen of ESPN.com. As Mortensen notes, a decision is expected to come quickly once the hearing completes, so we should know within the next couple days whether or not Beckham will be eligible to play this weekend.

With Washington and Philadelphia set to play on Saturday night, it’s possible the NFC East division crown will already be decided by the time the Giants’ kick off against the Vikings on Sunday, since Washington will clinch with a victory. But if the Eagles prevail on Saturday, Beckham’s suspension could loom large on Sunday, with the Giants’ season on the line.

Here’s more from around the NFC East:

• After Chip Kelly‘s weak endorsement of Eagles running back DeMarco Murray this weekend, Les Bowen of the Philadelphia Daily News is becoming more convinced that Murray’s time in Philadelphia could come to an end after just one season.
• Defensive coordinator Bill Davis shouldn’t have to shoulder all the blame for the Eagles‘ struggles on defense this season, but his job is on the line nonetheless, writes Jeff McLane of the Philadelphia Inquirer.
• A Federal Circuit ruling on Tuesday may have an impact on Washington‘s case regarding the Redskins trademark, as Bill Donahue of Law360 details. The Federal Circuit ruled that the government’s ban on “disparaging” trademark registrations is a violation of the First Amendment, striking down the provision that was used to strip Daniel Snyder’s franchise of the Redskins trademark.
• Per Aaron Wilson of the Houston Chronicle (Twitter link), Washington recently tried out a pair of tight ends, Andrew Gleichert and Brian Vogler, along with defensive tackle Kamal Johnson.

TUESDAY, 11:48am: The Patriots have made the move official, announcing in a press release that they’ve signed Jackson. To make room on the roster, New England cut defensive tackle Ishmaa’ily Kitchen, less than a week after signing him.

MONDAY, 10:07am: After featuring a three-headed rushing attack on Sunday that included Brandon Bolden, James White, and Joey Iosefa, the Patriots will add a veteran to the mix, according to Josina Anderson of ESPN.com, who reports (via Twitter) that the club will sign free agent running back Steven Jackson.

While Jackson had an excellent run in St. Louis, rushing for more than 1,000 yards in eight straight seasons and earning three Pro Bowl nods, he appeared to have lost a step during his two years with the Falcons. In 27 games with Atlanta, Jackson ran for 1,250 yards on 347 carries, an average of 3.6 yards per attempt. He was cut by the Falcons in February and there had been no reports of him working out for NFL teams since then, until he met with the Patriots last week.

With LeGarrette Blount and Dion Lewis lost for the year, the Patriots have been playing shorthanded in the backfield — White has played well, but is generally a pass-catching back, leaving Bolden and Iosefa to handle most of the carries. Iosefa hadn’t appeared in an NFL game prior to yesterday’s contest against the Titans, and Bolden is more of a special-teamer than a feature back, so Jackson will add some veteran depth to the roster.

According to Anderson (via Twitter), Jackson will be signing a one-year deal with the Pats, so he’s simply being viewed as a short-term option. The move may not bode well for Montee Ball‘s chances of reaching the active roster in the coming weeks — Ball remains on New England’s practice squad for now.

Matt Flynn waiting in the wings to face Jaguars in Week 16

New Orleans Saints quarterback Drew Brees said he will undergo an MRI on his foot after injuring it in the first half of the Saints 35-27 loss to the Lions on Monday night.

Brees limped to the sidelines after taking a hit and had his foot inspected and taped up by trainers. However, he never missed a snap and returned to the game shortly. (NOLA.com)

Nerdy Football Analysis: We’ll have to wait and see how the MRI shakes out. There’s nothing the Saints have left to play for, so we suspect they’ll sit him if anything is seriously wrong. Matt Flynn could be a decent plug-n-play QB if Brees misses Week 16.
