San Francisco 49ers quarterback Alex Smith has been dealing with a concussion this week, according to Comcast SportsNet Bay Area's Matt Maiocco. The news comes as a surprise to many since Smith didn't get the concussion during Sunday's game against the Dallas Cowboys.
Despite the concussion, Smith was a full participant in practice on Wednesday, according to The Sacramento Bee's Matt Barrows. Limited or missed practice time for Smith would be a detriment to the 49ers, who are already dealing with injuries to key receivers such as Braylon Edwards and Michael Crabtree. The former is out with a knee injury indefinitely after taking a hit during Sunday's game while the latter continues to deal with a nagging foot injury.
Crabtree may return this Sunday, but his return will be insignificant if Smith isn't around to throw him the ball. Thankfully, that doesn't look like a real possibility. Smith practiced without limitations on Wednesday and should be under center on Sunday.
