RENTON — Defensive lineman Leonard Williams, who for a brief moment thought he might have suffered a serious ankle injury last weekend in the 30-23 victory over the Chargers, is healthy for the NFC West showdown Sunday against the San Francisco 49ers and not listed on the team’s game status report.

“I feel good going into Sunday,” Williams told reporters Friday after practice.

Williams suffered the injury in the fourth quarter and was down on the turf for a few agonizing minutes.

“I just kind of heard a little bit of crunchiness in there when I went down, and just like the pain level of it at the time, I was hoping that it wasn’t something bad,” he said.

After being examined, Williams stayed on the sideline. He said Friday that if it had been a playoff game he could have returned.

After returning to practice on a limited basis Wednesday, Williams sat out on Thursday, leading to some questions about his status. But he confirmed that was a rest day and he practiced fully Friday and appears set to play a usual number of snaps Sunday.

The Seahawks also said safety Ty Okada is set to return after missing the first four games because of a hamstring injury. 

“He’s not rusty at all on the mental side, and he’s moving around great,” Seahawks coach Mike Macdonald said. “Looking forward to seeing him play.”

Macdonald said Rodney Thomas II — who replaced Okada in the starting lineup — also could play.

The only players Seattle declared out are running back Zach Charbonnet (who is still in return-to-practice status following an ACL injury suffered in January), rookie cornerback Julian Neal (hamstring) and backup linebacker Chazz Surratt (calf). Backup running back George Holani (rib, knee) and receiver Irv Charles (knee) are questionable.

Everyone else is good to go, which is good news for Seattle against the 4-0 49ers. 

A victory, and the Seahawks would take over first place in the NFC West because they would hold the tiebreaker advantage.

A defeat, and the Seahawks would fall two games back. They also would be in danger of losing the tiebreaker for the season.

The good news on Williams puts a positive end to a workweek that began with defensive players calling a players-only meeting in the wake of the sloppy ending to the Chargers game. Seattle was assessed 14 penalties for a team-record 150 yards.

Four personal fouls against the defense in the second half helped Los Angeles cut a 27-6 third-quarter deficit to 30-23 before Uchenna Nwosu’s strip sack of Justin Herbert sealed the victory.

Defensive leaders Williams, Jarran Reed, linebacker Ernest Jones IV and safety Julian Love called the meeting Monday.

The focus was the penalties, but players said additional topics were discussed.

“A couple of the other guys hit on the penalties,” Jones said. “I had other things that I wanted to focus on. We got through to each other. We talked, we had man-to-man conversations in that room. We have an understanding of what we have to do and what we need to do.”

Love said players were “just being real with each other” and called it “just a moment of clarity to just come together as the guys who are actually on the field doing the things.”

Asked what led to the meeting, Love said, “Just vibes. I think we have a good pulse of the guys in the locker room. It’s always interesting when you win a game and everyone is kind of feeling like a certain way after the game.”

Jones said one topic discussed was stressing the importance of clear communication on the field, especially with the 49ers — whose offense thrives on trying to confuse opponents — on tap.

“Could’ve been tighter on the communication on certain things [against the Chargers],” Jones said. “Getting in and out of checks. That’s going to be big this week. We carry a big crowd; they carry one, too. It’ll be a good game, a loud game. Communication is going to carry us through.”

• Seattle will have to make a move by Saturday to add Charles to the 53-man roster if he is to play against the 49ers. Charles was acquired in a trade with the Jets with the idea in part that he could play a gunner role on special teams. Seattle might need Charles to fill that role with Neal out. Macdonald said Neal was injured in practice Thursday.

• Signs continue to indicate that Charbonnet’s most likely return date is the Oct. 25 game against the Chiefs. Seattle plays at Denver on Thursday, which won’t give Charbonnet much practice time next week. 

• Macdonald said starting right guard Anthony Bradford is “doing great” as he recovers from knee and hip injuries that landed him on injured reserve. He is eligible to return to practice next week.  

• If Holani can’t play, then Robert Henry II, who was signed to the 53-man roster this week off Washington’s practice squad, might be active. “He’s done a nice job,” Macdonald said of Henry’s three practices this week.
