Niners LB Tatum Bethune suffered a high-ankle sprain in Sunday's win over the Cardinals. HC Kyle Shanahan said Monday that they expect Bethune to miss multiple weeks but that he probably won't hit IR because of the Week 14 bye.

The Broncos landed LB Dre Greenlaw in free agency with a three-year, $31.5 million deal. That positions him as Denver's highest-paid LB and marked a noteworthy investment into a 28-year-old (on May 25) who missed nearly all of last season coming off his Achilles' tear in the Super Bowl. The 49ers reportedly made a late push to retain Greenlaw. Instead, his move shakes up two LB groups.

Niners LB Dre Greenlaw appears likely to miss the final two games of the season with soreness in his calf. That's, of course, a more significant issue for Greenlaw than it might be for others because he's coming off an Achilles' tear from last year's Super Bowl. Greenlaw returned to play 30 snaps in Week 15, his first action since the injury. But he made it through just 4 snaps in Sunday's loss to the Dolphins.
