LOS ANGELES—Seahawks coach Pete Carroll said on Friday that defensive ends Jadeveon Clowney and Ziggy Ansah would both be game-day decisions, and when the Seahawks play the Rams Sunday night, one of the two will be on the field, while the other will not.

Clowney, who is dealing with a core muscle injury, is active, while Ansah, who sustained a stinger in last week's win over the Vikings, is inactive.

Starting strongside linebacker Mychal Kendricks, who was listed as doubtful with a hamstring injury, is inactive. Rookie Cody Barton is expected to take over the strongside role for Kendricks, though Carroll did note that this game could call for the Seahawks to play more nickel defense than they have in most games given Kendricks' absence and the personnel the Rams use on offense.

"It may cause us to have to play more nickel and stuff like that," Carroll said. "But Cody's a good player, we're anxious to see him contribute. He played quite a bit last week, more than he has been, and he's ready to go. 

"Cody is a particularly diligent worker and a smart kid, plays all three spots. He's a well-versed of a guy coming in as you could hope for for a young guy. We really don't have any hesitation in trusting that he can play."

Also out due to injury Sunday for the Seahawks are tight end Luke Willson (hamstring), cornerback Neiko Thorpe (core) and fullback Nick Bellore (quadriceps).

For the Rams starting right tackle Rob Havenstein and tight end Gerald Everett are inactive due to injury:
