Rashad Butler walked into camp as the Texans right tackle.
According to John McClain of the Houston Chronicle, Butler suffered a torn right triceps muscle and will be placed on injured reserve. He had the same injury in his left arm last year, costing him 14 games.
“It’s unfortunate, a tough, tough deal,” Texans coach Gary Kubiak said. “He comes back from the other injury, battles, does a heck of a job and handles himself like a big-time pro [when Newton named the starter]. You hurt for guys that work their tail off.”
The Texans will either use third-year tackle Andrew Gardner or find a veteran on the waiver wire for the swing tackle role.
