Texans starting right offensive tackle Tytus Howard left practice early with apparent heat-related issues as he was attended to by trainers.
This marked Howard's first practice back. The former first-round draft pick tested positive for COVID-19 last week, per a league source.
"When you come back from this ,it's always going to be a little bit of a ramp-up," Texans offensive line coach George Warhop said. "Before, he was in excellent shape. He wasn't having any issues. I think it's just a matter of days before he can get his wind back and then he'll be just fine."
Meanwhile, linebacker Garret Wallow, who's competing for a starting job, injured his left ankle in practice, per a source. The team will continue to evaluate Wallow, who was able to walk under his own power with a limp before being carted off with trainers.
The Texans like Wallow's intelligence, versatility and instincts. He's able to play all three linebacker spots.
A fifth-round draft pick from TCU last year, Wallow had 23 tackles, two for losses and one sack in 17 games and two starts. The former All-Big 12 selection had 15 solo tackles.
“I think he did a great job this offseason putting in the work, trying to change his body," Texans linebackers coach Miles Smith said. "His body fat level is way lower than it was. He has transformed his body, first and foremost. Year Two in the defensive system, he has repped at all three linebacker positions. He's showing his intelligence and natural ability."
Rookie offensive guard Kenyon Green remains sidelined with a knee injury after having offseason knee surgery on his lateral collateral ligament. The first-round draft pick from Texas A&M is keeping up with the Texans' playbook by attending meetings and learning all he can until his knee improves enough for him to resume practicing.
"He needs time," Warhop said. "Once he gets more time on task, I think everybody is going to be impressed with the player he's going to become. It's difficult in terms of what the situation is. He's now back in meetings, so he can get it that way.
"When you're not in the meetings, it's hard. When a guy has a sprained knee or a strained hamstring they're in the meetings all the time and you're coaching them like everybody else."
