The San Francisco 49ers didn't begin the preseason the way they wanted to.
Aldon Smith has been diagnosed with a hip bruise and will not return— Matt Barrows (@mattbarrows) August 11, 2012
Since the injury is so recent, there's no timetable for Smith's return.
Despite it being called a "bruise," there is cause for concern in San Francisco, as Smith was slated to be a starter for the 49ers after a monster rookie campaign in 2011.
Smith played in all 16 games for the Niners last season, recording 37 tackles, 14 sacks and two forced fumbles as a backup to Parys Haralson.
For now, we'll assume that Haralson will take over his spot as the starter until Smith is deemed healthy.
It's not hard to see why San Francisco decided to make the swap at linebacker, as Haralson had just 34 tackles and two sacks as a starter for the 49ers' defense in 2011.
With Smith being implemented as the starter for the 2012 season, he would be the only difference on the 49ers' defensive depth chart since they are returning the other 10 starters.
San Francisco's D is still nothing to mess with, but losing Smith makes it a little easier to deal with.
