Yes Kache had a good strip and fumble recovery against the Raiders tonight in the 4th quarter to turn the momentum. May get himself on the roster.

Linebacker Kache Palacio played the game of his life
Palacio was a longshot to make the Seahawks roster after they brought the undrafted free agent to training camp in early August. But the Washington State product has slowly ascended the depth chart.
On Thursday, in what served as his final audition to make the roster, Palacio tallied six tackles, one for loss, and forced and recovered a fumble.
"Big play, huge play," Carroll said. "He's done a nice job. He's kind of come out of nowhere. We got him kind of late. He jumped on the scene and showed the flexibility to play different positions. He'd already been an outside 'backer (at WSU). He's played inside for us as we've needed him, too, and worked hard on special teams."
It remains unclear whom he would replace, but there's no doubt he improved his stock as much as any player aiming for a roster spot.
