Per that report, the Texans "weren't happy with his work habits."

During camp, it was apparent Bill O’Brien wasn’t happy with Foreman. Asked after a practice about the third RB spot, O’Brien said, “Who’re the first two?” When Lamar Miller and Foreman were mentioned, he said, “Miller,” and went on to explain the backup job was “wide open.”
ESPN's Adam Schefter added that "Houston feels like Foreman needs a fresh start and needs to grow up."
Foreman, 23, showed potential in his rookie season in 2017, rushing for 327 yards and two touchdowns in 10 games as Lamar Miller's backup. He missed all but one game last year, however, with a torn Achilles.
He was expected to be a major part of Houston's offense in the 2019 season, and Texans running backs coach Danny Barrett praised him in early July, per Aaron Wilson of the Houston Chronicle:
"He's light-years ahead of where he was last year at this time, coming off the injury and everything. I still think he's continuing to work hard. I think he's had a good offseason to date. The time away from here, I thought was well spent for himself. Getting ready to go physically, and I think mentally, right now, is what I look at is each and every day.
Being consistent mentally as far as being locked in to what we're trying to do and improve on the little things and trying to get back to that form in which we saw prior to me coming into here, which was the 2017 season, his first year."
But Foreman has failed to impress since and found himself in head coach Bill O'Brien's doghouse:
With Foreman waived, Josh Ferguson, Buddy Howell, Taiwan Jones, Damarea Crockett and Karan Higdon Jr. will now battle for the backup running back position behind Miller.
