What do you think is really going on with Justin Smith? The way Harbaugh is handling it is odd, it seems like he is hiding something.
Here is a video with all of Justin Smith's plays during the 3rd Quarter of the Patriots game. Skip to 2:07 of the video to see the play that made him leave the game in the middle of a Patriots TD drive with 3 minutes left in the 3rd Quarter. 2:25 of the video shows his first and only play after he returned to the field in the 4th quarter.
They say that he went in to get an X-Ray on his elbow before returning to the sidelines with 14:20 left in the 4th quarter. He does not return to the field for the first series of the Pat's drive. He comes in at 12:30 after the Pats convert on 4th and 2 to the Niner's 45.
I am not too familiar with the ins-and-outs of Defensive Line play. Do you guys see anything here that indicates an arm or elbow issue? Does it look serious?
