The Oakland Raiders had four quarterbacks on the roster – much to the delight of the national media – for just under 24 hours, but following the placement of Nathan Peterman on the reserve/injured list Monday morning, that room trimmed to three.

"Well it was unfortunate, Nate Peterman hurt his elbow and we had to put him on IR," said Head Coach Jon Gruden following practice. "I'm a big believer that you have to take care of that position."

And the Raiders did just that following the initial wave of roster cuts, claiming DeShone Kizer via waivers after the athletic quarterback was cut by the Green Bay Packers. The Notre Dame-product has 15 starts under his belt, and now fills out the third spot in the quarterbacks' room, joining Derek Carr and Mike Glennon.

"Kizer is a guy that I liked coming out of Notre Dame," Gruden explained. "He's only 23 years old. He has 15, 16 starts. Started two games in the preseason this year for Green Bay, so he's had a lot of reps. He's had a lot of experiences. I'm sure most of his bad experiences, like Peterman, will be reported over and over. But I think he's got a big upside. He's athletic. I know [offensive coordinator] Greg [Olson] and I are looking forward to working with him. We have to fast track him. He has a lot to learn in a short period of time."

As Gruden said, with just seven days until the Silver and Black officially kick off the 2019 regular season, Kizer will have a busy week ahead of him, and while the likelihood of him entering into a game situation is slim to none – if everything goes to plan – No. 14 will still play a vital role as the Raiders prepare for Sundays.

"We need a quarterback that can move around and emulate [Patrick] Mahomes and DeShaun Watson," Gruden said. "Peterman was going to do that for us, the zone reads, all the things that he's able to do. Now Kizer gives us a dimension that will help us prepare for opponents. We think he's got some upside in our system."

Not only does Kizer's addition to the 53-man roster provide some immediate valuable in terms of preparing the Raiders' defense for different looks, but he also gives Gruden some added security at a premium position.

"I didn't like it," Gruden said when asked about carrying just two quarterbacks in 2018. "We went down to one quarterback last year and I almost jumped off the bridge. You have to shut down business if you don't have a backup quarterback. My brother went through it last year. I don't know how many quarterbacks they had to play. Some franchises go with two. They had a guy that stayed healthy for 10 years. I hope Derek [Carr] does that. This is no reflection on Derek, but I just think you have to have guys developing at that position. You have to have guys ready to go out and play. We have really good receivers. We have a good group of offensive lineman. We want to have a quarterback that can help everybody win."

Throughout his short career, Kizer has completed 275 passes for 3,081 yards, 11 touchdowns and 24 interceptions. The Silver and Black open the regular season on Monday, Sept. 9 against the Denver Broncos.
