Wallow suffered an ankle injury during Tuesday's practice session, Brooks Kubena of the Houston Chronicle reports.
Houston head coach Lovie Smith does not know the severity of the injury, but the coach doesn't believe Wallow's injury is a season-ending one. Wallow, a fifth-round pick in 2021, played mostly special teams as a rookie, but he was singled out by general manager Nick Caserio in June as a player that made great on-field and physical progress.
