The Seahawks sat and watched the lightning for an hour, then they watched their left tackle carted off.

Russell Okung just went to the locker room for X-rays on his left foot.

Okung was replaced by guard Paul McQuistan, who was promptly beaten for a sack by 49ers outside linebacker Aldon Smith.

Trying to get anything going against the 49ers was going to be tough, doing so without a Pro Bowler is going to be that much tougher.
