JACKSONVILLE – The Jaguars got bigger early Saturday.

They maybe gained some swagger, too.

The Jaguars on Saturday used their first fourth-round selection on Missouri offensive tackle Javon Foster. They used their second fourth-rounder on Louisiana State defensive tackle Jordan Jefferson, a college teammate of second-round defensive tackle Maason Smith.

“They’re getting two dominant dogs, man,” Jefferson said of he and Smith.

As Smith did Friday, Jefferson spoke highly of his relationship with Jaguars linebackers coach Matt House, LSU's defensive coordinator the past two seasons.

"He's a good coach," Jefferson said. "I feel like it's going to be good. I know those guys. I played with Maas. I feel like it's going to be basically one of the things where we're going to pick up where we left off."

Jefferson (6-feet-3, 313 pounds), the No. 116 overall selection, played four seasons at West Virginia before transferring to LSU for his final season. He played all 13 games for LSU in 2023 with six starts.

He registered 90 tackles in college with 21.5 tackles for loss and six sacks. He was invited to participate in the Senior Bowl in January.

"They're getting two guys that are going to cause disruption," Jefferson said of he and Smith. "Not only in the run game, but in the pass game as well. They're getting just all-around quality guys. They're getting some hard-working guys, guys who are going to show up to work every day and put forth all the effort.

"I want to come in and just help my team be successful any way they need me and anyway they want to play me."

Foster (6-feet-5, 313 pounds), the No. 114 overall selection, was a three-year starter at Missouri. He was a third-team All-America and third-team All-Southeastern Conference selection as a senior.

He called his selection Saturday "a dream come true."

"It's a blessing," he said. "I'm really glad this organization chose me. It's a great organization and it's going to be a fun ride."

Foster said he focused on basketball through his junior year in high school, with his father – Jerome – having played defensive line in the NFL from 1983-1987 for the Houston Oilers, Miami Dolphins and New York Jets. Jerome was a fifth-round selection by the Oilers in 1983.

"My dad was always telling me once I get on that football field, I'm going to fall in love with it," Javon Foster said. "He wasn't lying. It was like something I was missing my whole life. Ever since I started playing football, I quit basketball right after that.

"I kind of knew exactly where I wanted to go and what I wanted to be. It was a great experience, just playing football. I started off a little bit late. I also feel like that's what got me here. I feel like I'm always playing with a chip on my shoulder.

"I feel like I have some catching up to do and I always have to do something extra, some extra work, just so I can be up to the standard."

He said Jerome had a "huge role in my football journey."

"Once I finally got on that field, I was really just picking his brain ever since then, asking him different questions about the league, asking him different questions about how can I make my game better," he said. "He was just giving me all the answers he could and giving me anything that he knew.

"I really appreciate him for that. He's always been in my corner, coming to my games all the time, and it's just been a blessing to have him in my corner."
