Kyle Shanahan: 49ers will use committee approach to replace Nick Bosa

The 3-0 49ers have already had plenty of injuries this season. The biggest happened on Sunday, with defensive end Nick Bosa suffering a torn ACL in his knee."He had a pretty good idea of what we were going to find out today," coach Kyle Shanahan told reporters on Monday regarding Bosa's injury. "But obviously he is bummed out and down, but Nick can handle anything and he is going to handle it like he always does, which will be great. But obviously he was bummed out from it not being able to finish out this year, and especially how good of a year he was having so far."His absence leaves a massive void for the defense."You don't just replace a guy like Nick," Shanahan said. "It just puts â?? you know, everyone's got to continue to get better at everything. It's the same thing I'd be preaching if we did have Nick too. When you lose your better players, it gets harder, but I also expect throughout this year all of our players to get better as it goes. That's stressed even that much more when you lose a great one like Nick. Lots of guys obviously will have to step it up as it goes, but I believe that'll be more by committee than any...
