Dalvin Cook showed up for work Tuesday, on the day the Minnesota Vikings were scheduled to report to training camp. No, the running back does not yet have the new contract extension he wants. And no, in spite of the threat he reportedly made in June, there was never really a chance he was going to hold out of camp either way.

The traditional training camp holdout by a player entering the final year of his contract is not something you can expect to see much this year, and it has nothing to do with the coronavirus pandemic. The reason camp holdouts are mostly a thing of the past is what the league's new collective bargaining agreement, approved in March by owners and players, says about them. Here's the exact text in Article 8, Section 1(b):

A player shall not receive an Accrued Season for any League Year in which the player is under contract to a Club and in which (i) he failed to report to the Club's preseason training camp on that player's mandatory reporting date; or (ii) the player thereafter failed to perform his contract services for the Club for a material period of time, unless he demonstrates to the Impartial Arbitrator extreme personal hardship causing such failure to report or perform, such as severe illness or death in the family.

This was a priority for the owners in the last round of CBA talks. They wanted to stiffen penalties for training camp holdouts, and they did. The previous CBA stipulated that players could lose an accrued season only if they didn't show up to camp by the date 30 days before the team's first regular-season game. So, in Cook's case, that date would have been Aug. 14. Under the new CBA, it was Tuesday.

Why does this matter? Losing an accrued season affects a player's free-agency status. As a 2017 draft pick, Cook has accrued three seasons so far, and he needs four to be eligible for unrestricted free agency. If he didn't earn an accrued season for 2020, then next March he'd only be a restricted free agent, meaning the Vikings would have the right to match any offer he got from another team.

Now, even when the mandatory reporting date was later under the old rules, this didn't stop everyone. For example, last year, Cowboys running back Ezekiel Elliott held out well past that 30-days-before-the-season mark as he headed into his fourth year, which meant that if he would have hit free agency this past March he would have been a restricted free agent instead of an unrestricted one. Elliott didn't care, figuring his accomplishments over his first three seasons -- i.e., leading the league in rushing yards twice and in rushing yards per game in the other year -- would prevent restricted free agency from limiting his market. It didn't matter in the end, because he signed an extension with the Cowboys right before the season.

But a player like Cook, even as great as he is, can't assume the same thing Elliott could. Cook has missed 19 games because of injury in his three-year NFL career, and even if he were to put together an outstanding and healthy season, there's no way to be sure a team would be willing to outbid the Vikings for him and part with a second-round draft pick.

So Cook is there, as Joe Mixon almost certainly will be in Cincinnati and Alvin Kamara in New Orleans and George Kittle in San Francisco and all of the other guys who are going into the final years of their contracts and want new ones will be in the cities in which their teams play. Holding out a couple of days into camp carries a stiffer penalty than it ever used to carry, and it doesn't make sense unless you're a star quarterback or someone who can feel confident that restricted free agency wouldn't, well, restrict you.

Three other things to know about this new CBA feature:

Don't expect any "hold-ins," either. There are some around the league who believe a player in Cook's situation would show up for camp and just refuse to practice until a new deal is hammered out. It's possible, but go back and reread Article 8, Section 1(b) again and note where it says, "the player thereafter failed to perform his contract services for the Club for a material period of time." That's the part that would allow the team to dock the player an accrued season if he showed up and refused to practice or take part in mandatory team activities. Could a player in Cook's situation claim an injury? Sure. But if the team didn't believe him, or diagnose him as injured, the matter could end up in front of an arbitrator, who could rule in the team's favor and deny the player an accrued season.

Fines are stiffer, but not for Cook, Mixon, Kamara or Kittle. The new CBA raised the maximum fine for skipping training camp from $40,000 per day to $50,000 per day, but fines for players who are still on their rookie contracts are capped at $40,000 per day as long as they're not in their fifth-year option season. Any player drafted in 2017 is entering the fourth year of his rookie deal, so his fines stay at $40,000 per day if he skipped days. Not that it matters much, since the threat of losing an accrued season probably acts as a more significant deterrent.

Fines can't be waived. It used to be that if a player held out and ultimately agreed with the team on a new deal, custom dictated that the team would waive the fines. But as a result of the owners' desire to discourage camp holdouts, there's a provision in the new CBA that prohibits that from happening. Article 42, Section 1 says of camp fines, "For the avoidance of doubt, any such fines shall be mandatory, and shall not be reduced in amount or waived by the Club, in whole or in part, but must be paid by the player or deducted by the Club as provided in Section 5(b) of this Article." (Section 5(b) specifies the manner in which fines are collected.)
