Story summary

Nick Bosa, the star pass rusher for the San Francisco 49ers, injured his calf during practice on Thursday and is expected to miss several games, likely starting with Sunday’s match against Arizona. The injury occurred while Bosa was doing high knees as part of his warm-up routine. Although it isn’t believed to be long-term, Bosa won't go on injured reserve due to the team's limited spaces available for this designation.

The calf strain adds to a series of injuries affecting the 49ers’ defensive line; currently, seven players are sidelined at this position. Among those missing are Sam Okuayinonu and Alfred Collins, who sustained season-ending injuries, while others like C.J. West and James Thompson Jr. have been ruled out for several weeks due to surgeries.

Bosa’s girlfriend, model Ella Ailiff, posted a steamy dance video on TikTok the week before his injury, lip-syncing lyrics from the song “Nicole Kidman.” The 25-year-old edge rusher began dating Ailiff late last year while rehabilitating from an ACL tear suffered in Week 3 of the previous season.
