Dallas Cowboys star Trevon Diggs is set to lose a fortune.The cornerback has spent his offseason rehabbing a surgically-repaired knee for the second year in a row, having suffered a torn ACL before the third game of the 2023 NFL season.Diggs is set to lose a huge amount of money for his offseason rehab decisionGettyBack in April, Cowboys owner Jerry Jones made it clear that he wasn’t impressed with the program that Diggs followed last summer, especially as his most recent campaign was also cut short after 11 games for more surgery on the same knee.“He’s working hard. That’s very important because if he will be very good and diligent in his rehab process then he’ll get back quicker,” Jones, who is one of the richest owners in sport, said three months ago.“And when he does get back, he’ll be sounder. If he has not worked as hard, he is more subject to injury. He’s learned that one time.“I have a lot of hope that his actual rehab and experience from the time before is really helping him out. I think it is.”Those comments were seen as a not-so-subtle snipe at Diggs’ commitment to rehab in 2024, but it’s since been suggested that things would be different this time.Unfortunately, that doesn’t seem the case.According to a report from The Dallas Morning News, the Cowboys’ plan to withhold half-a-million dollars of the All-Pro’s salary, as he has not worked out enough with the organization in recent months.“Team officials will deduct $500,000 from Diggs’ $9million base salary for his failure to complete at least 84 per cent of his offseason workouts,” the outlet wrote, quoting a source familiar with the contract.The report, from Calvin Watkins, added that some NFL players have workout clauses in their contracts as a bonus for attending a certain percentage of sessions, or a penalty for not doing so.Watkins added that instead of doing a majority of his rehab work at the team’s practice facility in Frisco, Texas, Diggs has elected to work away from Cowboys HQ.It remains unclear why Diggs prefers to rehab away from the Cowboys practice facilityGettyJones previously questioned his decision to rehab away from the team in 2024GettyHe has not told the media if he has issues with the medical staff.Diggs, who was slammed for hitting the club last season with CeeDee Lamb, signed a five-year, $97m extension with the Cowboys in 2023.While he led the league in interceptions back in 2021, he has appeared in just 13 games over the past two seasons, and durability has become a concern.The 26-year-old did attended the mandatory veteran minicamp in June, where he was assessed by team doctors.Diggs also set himself the goal of being ready to return to action in Week 1 of the 2025 season, and head coach Brian Schottenheimer suggested last month that he is progressing well.“It’s going good,” Schottenheimer said.Diggs is targeting a return for Week 1 regardless of where he worked in the offseasonGetty“I talked to Trevon last week. He’s down in Miami doing some training.“No timeline for his return, but he had to come back a couple weeks ago to get checked out by the doc.“All signs are positive.”While Diggs is set to lose $500k of his base salary for his offseason rehab decisions, he could make that money back if he stays healthy in 2025.The cornerback has a $1m per game roster bonus, and will earn that figure if he plays all 17 weeks of the regular season. Diggs would also trigger a $300k escalator for five interceptions and making the playoffs, or a $700k escalator for seven interceptions and reaching the postseason.While the Cowboys will want to see Diggs on the field for every game, and the player himself would bank serious money if he can do that, it seems the two parties are currently at odds over how to get him back to full strength for 2025.Stay up to date with the latest from the NFL across all platforms – follow our NFL Facebook page, subscribe to our talkSPORT End Zone YouTube channel for all the offseason news, interviews and more
