The Jaguars were without starting weak-side linebacker Telvin Smith for the second consecutive practice Thursday.
The fourth-year player has been in the league's concussion protocol since the second half of the Jaguars' Week 12 loss to the Arizona Cardinals.
Smith suffered a head injury during the first half of last Sunday's game and reported symptoms at halftime.
If Smith can't play in the Week 13 matchup against the Indianapolis Colts, he will be replaced by a combination of starting middle linebacker Paul Posluszny and rookie Blair Brown.
Jaguars defensive coordinator Todd Wash said Posluszny is capable of handling the responsibilities of the nickel formation.
"Poz can play, it's just a situation where we have two other backers that are talented," Wash said Thursday. "We are comfortable with Poz in there, running our package and asking him to play the MIKE or WILL, just depending what's going on with the health situation of our linebackers."
Wash also expressed confidence in Brown.
"Depending on what happens with Telvin - we don't know yet - but if Telvin doesn't play, we've got to be able to count on Blair and he's got to go in and play well," Wash said.
Along with Smith, wide receiver Allen Hurns (ankle) also missed practice. The veteran has been held out of practice since suffering an injury at the end of the Week 10 win over the Los Angeles Chargers.
Quarterback Blake Bortles (wrist) and running back Leonard Fournette (ankle) were full participants in practice.
Wide receiver Marqise Lee (knee), cornerback Jalen Ramsey (ankle), safety Tashaun Gipson (knee), linebackers Donald Payne (hamstring) and Lerentee McCray (hamstring), guard Patrick Omameh (quad) and right tackle Jermey Parnell (knee) were limited participants.
Ngakoue motivated by curious Pro Bowl fan-vote totals
Jaguars defensive end Yannick Ngakoue owns the third-highest sack total (10) in the AFC this season.
He also leads the NFL with six forced fumbles. The next closest total is four by Tampa Bay Buccaneers linebacker Lavonte David.
Those numbers are typically seen as Pro Bowl stats for a whole 16-game season. Ngakoue has accomplished that production in just 11 games.
However, Ngakoue has not reached the top 10 at his position during the first two weeks of fan voting for the Pro Bowl.
"It's nothing to really worry about," Ngakoue said Thursday. "It is what it is."
The second-year player has totaled 18 sacks and 10 forced fumbles during his first 27 games in the NFL. Still, his name isn't recognized with the likes of his teammate Calais Campbell or New Orleans Saints defensive end Cameron Jordan.
Ngakoue has produced more sacks and forced fumbles than Jordan since he was drafted. However, Jordan is a former Pro Bowl selection with a more notable name.
The young player addressed the early voting results Wednesday night on Twitter.
They ask me why I have a chip on my shoulder?🙏🏾— YANNICK NGAKOUE! (@YannGetSacks91) November 29, 2017
We going off names? Or numbers? 😂— YANNICK NGAKOUE! (@YannGetSacks91) November 29, 2017
Ngakoue has offered up the production but he hasn't really had the exposure, which typically factors into the fan vote.
The Jaguars have been in one primetime game over the last two years. Ngakoue was also drafted in the third round as opposed to the first or second, which come with much more fanfare.
He has used his draft status as motivation in the past. This year's fan voting could be added to the chip on his shoulder moving forward.
"Not being talked about is just enough fuel in itself," Ngakoue said. "Other than that, just keep doing the same things I've been doing."
More News and Notes
- Wash on the defense's struggles against tight ends:
"I just think we've played some good tight ends. You have a good tight end, you try to get him [involved] in the passing game. Prior to this, maybe we didn't play many good tight ends as we are here late but obviously this week is a heck of a challenge with [Colts tight end Jack Doyle]."
- Offensive coordinator Nathaniel Hackett on running back Chris Ivory's recent struggles:
"I think that this last game, he only had one rep and that [fumble] really wasn't on him. It was one of those things where a block was missed upfront and it's kind of the feeling Blake [Bortles] has. You've got a 300-pound human being running right at you and that was just frustrating. I think all running backs want to get into a rhythm and I think for any guy that goes in, the more they can get going, the more they can feel it's going to pop, they can hit their landmarks, they can hit the line. I think when you don't get a ton of reps and a guy doesn't get in a flow, he might not get to where he wants to get. The idea is we just have to get him there faster and he's just got to trust it and believe it and roll."
- Special teams coordinator Joe DeCamillis on the game-ending kickoff laterals against the Cardinals:
"It's obviously different in different situations because they're going to put the ball in different places. I wish we would have gotten the throw the other way to the other side, a little bit further and maybe we would have had a different outcome. It's a tough play, no question about it."
