After a free-agent deal between New Orleans’ 2013 special-teams captain Will Herring and Dallas fell apart Friday, the player’s representative unloaded on the Cowboys, saying their behavior was “crazy” and “made no sense.”

Herring, a backup linebacker, had agreed to a one-year contract with Dallas on Thursday. But Dallas never announced the deal, and then news broke that it was off — according to Herring’s agent, George Mavrikes, the Cowboys reneged because they thought the player “may be an injury risk.”

“I’m very angry with Dallas,” Mavrikes said in an email. “(Herring) passed the physical ... . He is healthier than 90 percent (of the league). He hasn’t missed a game or a practice the last two years,” and he’s only missed a handful of contests throughout his career, which began in 2007.

Herring has missed 15 of 112 regular-season games possible. He’s suited up for the Saints’ last 32 regular-season games as well as two playoff contests in January.

Herring led the Saints’ special teams unit in tackles and forced a fumble. Rotating in at inside linebacker on defense, he also intercepted a pass in a Week 4 win vs. Miami and had six solo tackles.

“They need solid players like him,” Mavrikes said of the Cowboys. “Fairly priced, never an issue off the field, can play (outside linebacker), was special-teams captain, plays great against the pass and most of all, doesn’t get hurt.

“Which is why they said they want out of the deal they agreed to. It’s crazy and makes no sense. He’s the exact player Dallas needs.”

It didn’t appear Friday that Dallas had commented on the situation with Herring. Cowboys beat writer Clarence Hill of the Fort Worth, Texas, Star-Telegram reported on Twitter he was hearing both Herring and Dallas supposedly had a “change of heart.”

Herring is again a free agent. His contract with Dallas was supposed to be for one year and $1.02 million, with a $65,000 signing bonus and $300,000 in total guarantees, USA Today’s Tom Pelissero had reported Friday.

Perhaps there’s a silver lining in the whole ordeal: Herring won’t be joining a defense that was ranked last in 2013 and in a Nov. 10 road loss to the Saints allowed New Orleans to set NFL and franchise records with 40 first downs and 625 yards of offense, respectively.

Herring on Friday remarked via Twitter, “The bad news is I’m not signing with Dallas. The good news is Jesus still sits on the throne. I hate it didn’t work out. Wish them the best.”

He arrived in New Orleans in 2011 after four seasons with Seattle.
