Doing much better had a good night's sleep last night. And and symptoms were. Positive. Today. Let it play out. There's there's a progression has to be. And I -- -- -- to be going through. Forward you know anyway so. -- Well. Have not much sympathy for the niners life out of Chicago's Jay Cutler suffered his own concussion on Sunday and like Smith he is far from certain to play Monday night difference here is Cutler has a long history of head injuries so. Coach Lovie Smith of the Bears staff we'll exercise utmost caution. In evaluating their quarterback. Scary concussions little bit different I just know doing that game last night. Guy has symptoms has a concussion but I don't play a man. We'll go to the protocol once they've been cleared to come back for practice. And of course to play that's when they'll play is really as simple as that. At quarterback obviously concerned for the niners but all of a sudden shockingly so is the run defense that allowed hundred yard rushers. In three of the last four games including Stephen Jackson. On Sunday insider -- -- go what kids. The 49ers ranked defense isn't up to the level as it was a year ago. But the team still considers it one of the strengths the 49ers front seven had a rough first half against the St. Louis Rams on Sunday as Stephen Jackson ran for nearly five yards a carry. But in the second half and overtime the run defense really strengthen. They allowed the Rams only three yards a carry so going into the second half of the season with foreigners still expect their run defense that helped him lead the way.
