The Kansas City Chiefs opened the 21-day practice window for running back Clyde Edwards-Helaire.
The Chiefs' transaction came on Wednesday. They will have 21 days to activate or shut down Edwards-Helaire, who began the season on the reserve/non-football illness list.
In August, Edwards-Helaire revealed on social media and also shared with reporters at training camp that he has been impacted by post-traumatic stress disorder since December 2018.
"Sometimes I'm admitted into the hospital, something like I can't stop throwing up and it's just, I (don't) know (anything) pretty much to stop it," he said, per ESPN.
"Real bad dehydration ... but it's really just mentally just not being there," he said, adding alert teammates can notice that, "'OK, Clyde's not laughing, he's not giggling, he's not himself.'"
Edwards-Helaire, 25, did not disclose the cause of his PTSD, other than to cite "a self-defense situation" that he went through in college.
The Chiefs (4-0) are adjusting to the loss of running back Isiah Pacheco, who underwent surgery on his fractured fibula last month and is expected be sidelined until at least November.
Kareem Hunt rushed for 69 yards and fellow running back Samaje Perine scored a touchdown in Kansas City's 17-10 victory over the Los Angeles Chargers on Sunday.
The Chiefs selected Edwards-Helaire in the first round of the 2020 NFL Draft out of LSU. In 48 games (32 starts) over four seasons, he has rushed 441 times for 1,845 yards with 12 touchdowns. He's added 765 receiving yards and seven scores.
Kansas City hosts the New Orleans Saints (2-2) on Monday night.
