San Francisco 49ers defensive end Yetur Gross-Matos is week-to-week with a knee injury sustained during the preseason finale against the Raiders, where he did not return after the first quarter. Head coach Kyle Shanahan indicated that Gross-Matos avoided a serious ACL injury but his status for the season opener remains uncertain. Gross-Matos was signed this offseason to bolster the defensive line, but with Leonard Floyd also injured and Drake Jackson out for the year, the team's depth at defensive end is a growing concern. Currently, only two healthy defensive ends are available, which could impact the 49ers' playoff aspirations. The results of Gross-Matos' MRI are expected to provide further clarity on his condition. The team may need to consider additional defensive linemen to ensure they can sustain their performance throughout the season.
