NASHVILLE – The Titans returned to the practice field on Friday for final preparations for Sunday's game against the Chicago Bears.

Some quick hits on the latest developments …

-Punter Brett Kern, who suffered a wrist injury in Sunday's game at Cincinnati, did not practice for the third day in a row and he's also been ruled out for Sunday. Titans Coach Mike Vrabel indicated on Friday the team plans to add another punter to the roster for Sunday's game. "We'll have some guys come in here tomorrow and see how they kick the ball," Vrabel said. "And then we'll pick one and go with them for the game."

-Receiver Adam Humphries, who suffered a concussion in Sunday's game, has been ruled out for the game against Chicago. Vrabel said the Titans take the concussion protocol very seriously.

"There's zero pressure for them to get back quicker than what they should," Vrabel said. "Having been through that as a player, I think I'm very understanding of that and try and explain that to the player. We'll continue to monitor (Adam) and continue to work him through the protocol."

-Receiver A.J. Brown, who did not practice on Thursday because of a knee injury, was back at practice and he's good to go for Sunday.

-Outside linebacker Jadeveon Clowney (knee) did not practice for the third straight day and his status for Sunday is to be determined. He's listed as questionable for Sunday's game.

"We're just trying to do what is best for him, and what's best for the football team," Vrabel said of Clowney, "and that was to give him a couple of days of rest. We'll see where he's at tomorrow and at 10:30 Sunday (when the inactives are due) make a decision on the 48 guys that go to the game."

-Right tackle Dennis Kelly (knee) was back at practice on Friday after missing Wednesday and Thursday. He's good to go.

-Defensive lineman Jeffery Simmons (ankle) was on the practice field for the stretch portion, be he went inside early. Simmons missed practices on Wednesday and Thursday.

-CB Kareem Orr (illness) practiced once again on Friday and he's good to go.

-S Dane Cruikshank (groin) practiced again as well and he's good to go.

-OL Daniel Munyer (hand) also practiced on Friday and he's good to go.

-CB Tye Smith (shoulder) did not practice on Friday and he's listed as questionable for Sunday's game.

-Cornerback Desmond King II, acquired on Monday via a trade with the Chargers, still isn't practicing but he continues to go through virtual meetings with the team. Vrabel said "there's some potential for him to be out there" on Sunday. King is expected to be in Nashville on Saturday.

-Cornerback Adoree' Jackson did not practice again on Friday, his second straight missed day this week because of the knee injury he's been dealing with since the start of September. The Titans moved Jackson to the 'Designated for Return' list last month. This designation opened up a three-week window for Jackson to practice with the team, and he will not count against the team's 53-man roster until being activated from injured reserve. This is the the third practice week for Jackson, and the Titans. But since Jackson returned on a Wednesday, the team has until next Wednesday to make a roster decision on Jackson. Vrabel said he expects Jackson to play at some point this season, but right now he's not sure when. Jackson is not listed on the injury report since he's not on the team's 53-man roster.

"It's all about the player and his health, and his ability to do his job, and to do it well, up to the expectations that we have," Vrabel said. "We'll make the decision whenever we have to. … I don't anticipate this being something that would keep him from the season, but I've always tried not to give timetables on anything because people react differently to injuries."

-Titans rookie tackle Isaiah Wilson went through his second full week of practice this week.

-Running back Senorise Perry, placed on the 'Designated for Return' list last week, also practiced again on Friday.

-Vrabel mentioned outside linebacker Tuzar Skipper, who played collegiately at Toledo, as a player who could potentially be elevated from the practice squad for Sunday's game.

-The Bears released their final Injury Report on Friday: DT John Jenkins (ankle), OL Sam Mustipher (knee), DE Roy Robertson-Harris (shoulder) and QB Mitchell Trubisky (right shoulder) are all out for Sunday's game. TE Cole Kmet (groin) is questionable.

-After pausing all in-person football activities and closing the team facility on Thursday after another player tested positive for COVID-19, the Bears were back in their building and practicing on Friday.

-The Titans are scheduled to hold a walkthrough on Saturday leading up to Sunday's game.
