Nick Bosa Injury update: 49ers pass rusher tweaked hamstring during drills

NFL Draft 2019: Nick Bosa stopped political tweets in case he ends up in San Francisco

The 49ers’ top pick is already battling an injury.

San Francisco rookie pass rusher Nick Bosa tweaked his hamstring in practice Tuesday. Coach Kyle Shanahan confirmed the injury occurred during one-on-one drills. While Bosa did not leave the field, he did not finish practice and walked with a limp following the incident.

“I know it was his hamstring, but I’m not sure of the severity of it,” Shanahan said after practice concluded.

San Francisco selected Bosa with the No. 2 overall pick in the 2019 NFL Draft. The Ohio State product entered 2018-19 as one of the top prospects in the country, but was sidelined with a core injury after playing just three games in his junior season. 

Bosa underwent core muscle surgery following the injury and elected to withdraw from school following the operation to prepare for the draft rather than finish out the season with the Buckeyes.

Bosa posted 17 1/2 career sacks in 29 games at Ohio State and will be crucial to the 49ers improving upon last season’s 4-12 finish.
