Wisconsin Badgers defensive lineman James Thompson Jr. is expected to miss the entire 2024 season due to an upper-body injury that required surgery. Head coach Luke Fickell expressed doubt about Thompson's return, citing a recovery timeline of four to five months. Thompson, who was the most experienced lineman on the team with 29 tackles last season, has started 18 games over the past two years. This injury significantly impacts Wisconsin's defensive strength as they prepare for their season opener against Western Michigan. The team has added transfers at the position but will need to rely on their depth to compensate for Thompson's loss. Wisconsin is also opening the season outside the AP Top 25 for the first time since 2016.
