It's one of those things that, like Coach Harbaugh always tells us, he's tougher than a two dollar steak. We know he's going to be all right. We know we have a bunch of great coaches here that keep everything on track, and we're going to practice today as if he was here.
Willis added (via Rob Gloster of Bloomberg.com), "We didn’t know he was having that done until just a second ago."
Harbaugh clearly does not want his players worrying about his health, and that is probably for the best. On that same token, he would not want them worrying pointlessly about their quarterback situation.
For the umpteenth time, quarterback Alex Smith's starting job has been brought into question by the media. Harbaugh has staunchly supported Smith since he came to San Francisco, and he has been right to do so. Calling criticisms of Smith out of date would be an understatement at this point.
Calling Smith only above average would be another understatement. With a whopping 70 percent completions and 104.1 quarterback rating, Smith is having the best season of his career.
With the recent concussion, Smith with have to pass medical tests before he can play. Thus, he could miss Monday's game against the Bears, which would be a temporary blow to the team. Nevertheless, there will not be even the tiniest hint of a quarterback controversy within that locker room.
No matter what backup quarterback Colin Kaepernick does on Monday—assuming he plays—it will not matter. It is analogous to Matt Flynn filling in for Aaron Rodgers in Green Bay for a game in 2011. Kaepernick can have the game of his life; Smith will still be the starter.
Fans can worry, the media can worry, but Harbaugh knows not to worry. Even if the 49ers lose on Monday night, they know they have Smith coming back soon enough, and they know they are far and away the best team in the NFC West.
So don't worry too much about Harbaugh or Smith, and don't worry about the 49ers this weekend.
