Quick Summary

The San Francisco 49ers are facing another significant injury setback with star player Nick Bosa expected to miss a few weeks due to a calf strain. This comes at a critical time as the team is already short-handed in its defensive line, with five out of ten players sidelined by injuries. Head coach Kyle Shanahan acknowledges the challenge of losing Bosa, described as irreplaceable and crucial for their defense's effectiveness against Sunday’s game against the Arizona Cardinals.

Story summary

The San Francisco 49ers faced another blow when star defensive end Nick Bosa suffered a calf injury during practice on Thursday, causing him to miss Sunday's game against the Cardinals and potentially several more weeks. Coach Kyle Shanahan announced that Bosa is expected to be out for "around a few weeks." The team already has seven players designated to return from injured reserve (IR), leaving little room for additional injuries before they max out their eight available IR spots. To mitigate the impact, the 49ers signed defensive tackle Naquan Jones off the Vikings’ practice squad but will likely need to elevate more players or seek outside help to field a full roster for Sunday's game.

🔮 Will Richard freed up Curry with a hard screen of Matisse Thybulle about four minutes into the fourth quarter, Curry received a pass from Draymond Green and buried a wide-open triple. The bucket was Curry’s eighth 3-pointer of the night and was good for his 25th, 26th and 27th points.
🔮 So, you could say they’re making progress, at least.
🔮 Curry finished with 44, and the Warriors needed every last one of them to hold off the Timberwolves, despite Golden State pulling ahead by 24 after halftime and Minnesota playing its first game since Anthony Edwards learned he would require knee surgery.
🔮 It appeared that a game that began without Edwards could end with Curry sitting on the bench, comfortably resting after building a big lead.
🔮 For most 49ers players, the bye week will give them some much-needed rest and relaxation.
🔮 Some 24 hours later, though, Shanahan had no update to deliver when asked if Pineiro’s struggles would lead San Francisco to try out other kickers over its bye week.
🔮 Nine different Falcons caught passes from Penix, who operated at will under little duress from the Niners’ defensive line, allowing his receivers to get open.
🔮 A decade and four other coordinators later, Morris just might be the final coach to find a seat in the 49ers’ game of musical chairs to fill the position leading their defense.
🔮 How often in the Kyle Shanahan era could we say the 49ers weren’t built to win a shootout?
🔮 Less than 24 hours later, the Warriors will have to do it all again in Phoenix, still in search of their first win.

San Francisco already made one move to stem the losses by signing defensive tackle Naquan Jones off the Vikings’ practice squad, but they’ll have to do more just to have enough bodies on Sunday, whether it be elevating someone like Sebastian Valdez off their practice squad or bringing in outside help.

they → feel → Dolphins
