The Seahawks spent most of the day beating themselves.

Finally though they turned their attention to the visiting Tennessee Titans.

And down the stretch they made just enough plays to get it done earning a 20-13 victory in front of 68127 at CenturyLink Field and win their 11th straight home game the longest current streak in the NFL.

A Seattle defense that a week ago allowed 34 points didn’t give up a single offensive touchdown to the Titans who scored only on a bizarre return of a fumbled field goal snap as time ran out on the first half.

That Tennessee score combined with a few other assorted Seattle mistakes had the Seahawks locked in a 10-10 tie heading into the fourth quarter.

But the Seahawks (5-1) drove for a field goal to start the quarter to take the lead and then got the ball right back on a Richard Sherman interception on Tennessee’s initial play of its next drive.

The Seahawks then quickly drove 59 yards capped by a 3-yard Marshawn Lynch scoring run with 7:33 left to finally grab control of a game that for much of the day was as chaotic as a kindergarten class at recess.

Tennessee (3-3) cut the lead to 20-13 on a 25-yard field goal by Rob Bironas with 2:18 left.

But the Seahawks benefitted from a Titans offside penalty on third-and-four to run out the clock.

The madcaps were typified by the play on which Tennessee scored its only touchdown.

The play was set up when Seattle’s kicker Steven Hauschka was forced to leave the game after suffering a concussion when he was run over by Tennessee returner Darius Reynaud on the kickoff following the Seahawks’ first touchdown with 2:41 left in the second quarter.

Hauschka was taken to the locker room and evaluated for a possible concussion also appearing to have suffered a nose injury.

And that meant punter Jon Ryan — usually the team’s holder — had to try a field goal on the final play of the half after Seattle had driven to the 3.

Seattle had used two of its timeouts in an attempt to get the ball back then had to use its final timeout to save 10 seconds after James Carpenter was called for a false start.

The Seahawks moved to the three-yard-line but Russell Wilson was forced to hurriedly down the ball on a second-down play to stop the clock with two seconds left.
