What happened: Testing confirmed the injury after Henningsen was carted off during Friday's training-camp practice. Denver placed him on injured reserve over the weekend.
Why it matters: The injury removes a candidate for Denver's seventh defensive-line spot. Henningsen's previous Achilles tear occurred during an August 2025 joint practice with the San Francisco 49ers.
By the numbers: Henningsen recorded 40 tackles, two tackles for loss and one sack across 34 games in 2022 and 2023. He had 91 tackles, 13 tackles for loss and eight sacks in 42 games at Wisconsin.
What to watch: Denver must settle its defensive-line rotation without Henningsen as roster cuts approach.
