San Francisco 49ers defensive ends Leonard Floyd and Yetur Gross-Matos both sustained knee injuries during Friday night's preseason finale against the Las Vegas Raiders. Both players are scheduled for MRIs to determine the extent of their injuries, which has raised concerns given the team's already thin defensive end position. Floyd, signed this offseason, left the game in the first quarter after a teammate fell on his leg but was later seen moving around on the sideline, suggesting a potentially less severe injury. Gross-Matos, also a recent acquisition, was injured shortly after Floyd. With Drake Jackson out for the season and Robert Beal Jr. underperforming, the 49ers may need to seek additional defensive end support. Head coach Kyle Shanahan expressed hope for positive news regarding Floyd and Gross-Matos, whose health is crucial ahead of the 2024 NFL season kickoff in two weeks.
