The Giants have officially ruled rookie QB Jaxson Dart out for Sunday’s game against the Green Bay Packers.

Dart has been expected to remain sidelined for the contest all week. 

The youngster is making his way through the five-step concussion protocol, but he hasn’t made enough progress to be fully cleared for his return just yet. 

The fact that he was able to get back out on the practice field and do some stretching during Friday's session is a potentially encouraging sign for his status heading into next week. 

For now, though, Big Blue will turn things over to veteran Jameis Winston.

Interim head coach Mike Kafka announced during the week that Winston had jumped over Russell Wilson on the depth chart and would receive the start if Dart could not go. 

The 31-year-old has mainly served as a backup over the past few seasons, but he has plenty of experience under center having spent the first five years of his career as the starter in Tampa. 

He has a career 61.2 completion percentage, 3,178 passing yards, and 54 touchdowns. 

“I’m grateful,” Winston said. “I get to be the starting quarterback for the New York Giants for this week -- when you get a chance to get opportunities like this, you do your best to capitalize and stay present and just do all you can do.”
