Bosa leaves with groin injury

Niners EDGE Nick Bosa left at halftime of Sunday's win over the Panthers with a groin issue. Here's what HC Kyle Shanahan said afterward, according to ESPN.com: "He started feeling it, it was a little tight all day. In the 2nd quarter, you could see him coming off the field. We looked into it at halftime -- he didn't feel like he could go." The team expects to test the injury further on Monday, but it doesn't sound like it's believed to be serious. We'll watch for updates.
