Knee leaves Bridgewater in question. And news on offensive line, Byron Jones, Eichenberg

While the Dolphins will definitely be without their starting right tackle (Austin Jackson) and likely without their starting left tackle (Terron Armstead) on Sunday against the 49ers, the status of their backup quarterback remains in doubt.

Teddy Bridgewater, who has missed two games with a knee injury, was listed as questionable. He was limited in practice for a third day in a row on Friday.

Coach Mike McDaniel said Friday he’s not sure whether Bridgewater will be ready to make his return and serve as the backup quarterback on Sunday.

In Bridgewater’s absence, rookie Skylar Thompson has been used the Dolphins’ backup quarterback behind starter Tua Tagovailoa in the last two games.

“He’s working through it. We’ll see,” McDaniel said Friday when asked about Bridgewater’s status for Sunday’s game against the 49ers. “He’s still on top of the game plan as much as he always is, if not more. But he’s balancing this time, spending more time than they ever has in the training room trying to get right. But, you know, we’ll we’ll see how it responds and I’m ready for either [backup quarterback].”

Also on the injury report, Jackson was listed as out and Armstead was listed as doubtful, meaning Greg Little and Brandon Shell likely will be the team’s two starting tackles on Sunday.

Running back Myles Gaskin — who is nursing shoulder and ankle injuries - was limited for the third day in a row and is listed as questionable. But Raheem Mostert, who missed last Sunday’s game with a knee injury, is no longer on the injury report and will play against his former team on Sunday, likely sharing time with fellow 49ers running back Jeff Wilson Jr.

As for cornerback Byron Jones, he won’t travel with the Dolphins to the West Coast for the two-game trip in California against the 49ers on Sunday and Los Angeles Chargers on Dec. 11. Jones has yet to play this season after undergoing surgery in the ankle/Achilles area in March.

“He’s focused on getting right,” McDaniel said to reporters when asked about Jones. “... Just when you guys don’t expect it, that’s when you’ll see him. You know what? He actually told me, he’s only going to come back when you guys stop asking me.”

Dolphins left guard Liam Eichenberg, who will miss his fourth game in a row Sunday after injuring his knee in the team’s win against the Detroit Lions on Oct. 30, is eligible to come off the injured reserve and make his return next week against the Chargers. But McDaniel said Friday that the timetable for Eichenberg’s return is still being worked out.

“I don’t really totally know at this point the exact date,” McDaniel said when asked whether Eichenberg will be ready to play in time for next week’s game against the Chargers. “I know he’s working hard. He got injured when his game was as strong as it’s ever been. He was making some plays, doing his job well. I think he’s very confident. Because of that, I think we’ll see him sooner than later. As far as if that’s next week or the following, I don’t know.”

ROAD TRIP

The Dolphins will fly to California on Friday and stay there for more than a week as they begin a two-game trip on Sunday against the 49ers before traveling within the state to take on the Los Angeles Chargers on Dec. 11.

That will keep the Dolphins away from home for a while, but it will also give players a chance to further develop relationships beyond the football field.

“This is a great opportunity for our team to bond,” Dolphins quarterback Tua Tagovailoa said. “We’ll be out there and it’ll just be us and I would say, as captains and with our leadership council group, we don’t think that it’s necessary that when we do get downtime away from football, guys stay in their room or ‘hey, I’m tired.’ Like no dude, you can sleep when it’s time for you to sleep.

“Let’s get guys to go out and let’s do things with our guys, whether that’s finding a basketball game to go to, trying to find a box, trying to go rent out a movie theater, trying to go watch a baseball game, whatever that may be, Top Golf. I don’t know. We’ll try to find some things that we can do that’ll help us get closer with our guys on this team.”

PING-PONG TABLE RETURNS

Just as the team heads out on a nine-day road trip, a ping-pong table was back in the Dolphins’ locker-room on Friday for the first time since it was removed after the team lost two in a row to fall to 3-2.

Miami lost the following week but has won five in a row since.

When the table was initially removed, McDaniel explained it this way: “Tyreek [Hill] and the captains decided that they wanted to take a step forward with all their opponent prep with regard to the team and with their preparation with our game plans in general. So he made the move to take the ping pong tables out of the locker room.”

Hill same playfully at the time that he simply wanted to upgrade the quality of the table and order a custom-made one. He did have a custom-made table delivered to his home in recent weeks, but that wasn’t believed to be the one in the locker room on Friday.
