49ers First-Round DE Nick Bosa Has “Serious” Ankle Sprain, Out For At Least Preseason



49ers GM John Lynch said Thursday in an interview with KNBR that first-round DE Nick Bosa has a “significant” ankle sprain and will miss at least the preseason, per Nick Wagoner

According to Lynch, Bosa’s ankle sprain is more significant than the earlier report suggested and there are “elements” of a high ankle sprain but it’s not a “full-blown” high ankle sprain.

When asked if Bosa is injury prone, Lynch said (per Matt Barrows): “We don’t feel he is injury prone…. Yesterday he had a big human being fall on his leg while he was engaged with someone else.

According to Ian Rapoport, an MRI on 49ers first-round DE Nick Bosa‘s ankle showed that he’s dealing with “just an ankle sprain.”

Rapoport says the 49ers plan to be cautious with their top pick and it’s possible he’ll be held out of preseason games.

Bosa was held out of OTAs with a Grade 1 hamstring strain, so it’s been an injury-filled summer for the young defensive end.

Even so, it makes sense to be cautious with Bosa and give him the time he needs to get healthy for his first season in the NFL.

Bosa, 21, was selected by the 49ers with the No. 2 overall pick in the 2019 NFL Draft by the 49ers. He agreed to a four-year, $33,551,874 rookie contract that includes $22,421,364 signing bonus. 

Last year, Bosa suffered a core muscle injury that has kept him sidelined and he decided it was best to not risk further injury and sat out the remainder of the season. 

During his college career at Ohio State, Bosa recorded 77 tackles, 29 tackles for a loss, 17.5 sacks, two forced fumbles, two pass defenses and a defensive touchdown over the course of three seasons and 29 games.
