Giants quarterback Jaxson Dart remains in the concussion protocol and has been ruled out for Sunday's game against the Lions in Detroit, interim head coach Mike Kafka announced before Friday's practice.

Veteran Jameis Winston will start his second consecutive game. Russell Wilson will be the backup.

"He's just in the protocol, and he's just working through that phasing of it," Kafka said of Dart. "So, based on the testing and the results, we're declaring him out for this week."

Dart, the No. 25 overall draft pick, has been a limited, non-contact participant in practice this week.

"The reps and all that stuff, I'll kind of keep it in-house," Kafka said when asked if Dart took any first-team reps this week. "But Jaxson got some work with those groups as well as Jameis."

Dart did not practice last week in the immediate wake of suffering the concussion against the Bears.

"My only concern was just making sure Jaxson's healthy and right," Kafka said. "Again, we have a lot of trust in the doctors. We have a lot of trust in that process, going through the concussion process. I know myself, I've had a couple concussions over the course of my career and you just want to feel comfortable and good. So, I think having that trust and understanding that everyone's just looking out for your best interest is important and we are certainly doing that with Jaxson.

"Wherever he ends up getting to in this concussion protocol, which is, again, this very vague term that, again, as a coach, I'm not a medical professional, so I'm not going to speak on the process, but I trust it. Some of our best people in the medicine world are in it, and they're giving him great opinions and making sure everybody who has to go through this process is in the right shape."

Making his Giants debut last week, Winston completed 19 of 29 passes for 201 yards and an interception by Evan Williams on third-and-six from the Packers 14-yard line with 36 seconds remaining in the game. Winston was looking for Jalin Hyatt in the end zone while the Packers held a seven-point lead. Winston also had three carries for 10 yards and a touchdown.

Dart, the NFL Offensive Rookie of the Month for October, became the first quarterback in NFL history with a touchdown run in five consecutive games, breaking a tie with Cam Newton (2011).

Dart has five games with at least one passing touchdown and one rushing touchdown in 2025, tied with reigning MVP Josh Allen for most in the NFL entering Week 12.

"The beauty of Jameis, the beauty of our group on offense and defense and special teams is our guys prep," Kafka said. "They put the work in. They're preparing themselves to play. Whether they're a practice squad guy or they're a backup in a primary role, they're preparing and they're asking questions and they're detailing out their work throughout the work week. So, no surprise to me that Jameis is ready to go. I have full confidence in him, just like I did last week, and we'll just keep on carrying on and Jameis will carry the torch for the group."

In addition to Dart, the Giants ruled out cornerback Paulson Adebo (knee), tight end Thomas Fidone II (foot), and outside linebacker Kayvon Thibodeaux (shoulder). Cornerback Deonte Banks (hip), running back Eric Gray (knee), and safety Tyler Nubin (neck) were listed as questionable on the final injury report of the week.
