Washington Commanders fans were nervous heading into Sunday's game against the Carolina Panthers. After a 46-yard run on Washington's first drive, rookie quarterback Jayden Daniels appeared to be in pain.

Daniels finished the drive but then went to the locker room with a rib injury. Washington said it was questionable whether he would return. The Commanders were leading 10-0 when Daniels left the game.

Marcus Mariota replaced Daniels, and while he struggled on his first drive, he quickly got hot and led Washington on several scoring drives, including a touchdown before halftime to make it 27-0. As the third quarter began, the Commanders shut out Daniels.

Daniels returned to the field in the third quarter to cheers from fans. A positive sign, right? He also looked in good spirits for the rest of the game. After Washington defeated Carolina 40-7, Quinn gave the following update on Daniels:

“I can't give you an update on Jayden, but I will as soon as we find out,” Quinn said. “We will do a few more tests tomorrow and then when we meet in the afternoon we will give you an update.” But I have nothing for everyone else who asks the same thing; same answer. So I just wanted to make sure I was completely clear on that.”

Quinn will speak to the media Monday afternoon at 3:30 p.m. ET.

However, Daniels' mother tweeted during Sunday's game that her son was “doing well.”

ESPN NFL insider Jeremy Fowler offered another positive update on Washington's star rookie.

With Daniels, the commanders play it particularly safe. It will be difficult to keep him out of next week's game against the Bears, but if he isn't 100%, Washington will go with Mariota. Quinn understands that there is nothing more important to the franchise than the short- and long-term health of Daniels.
