JACKSONVILLE – Jamaal Charles has joined the Jaguars.

The four-time Pro Bowl running back's signing Tuesday afternoon highlighted a day featuring multiple Jaguars roster moves in the wake of recent offensive injuries.

Charles, an 11-year NFL veteran who previously played with the Kansas City Chiefs and Denver Broncos, signed on the same day the Jaguars signed running back Dave Williams from the Broncos' practice squad and elevated tight end David Grinnage from their own practice squad.

"I've been doing my training work and staying in shape in case I got anybody's call," Charles told jaguars.com Tuesday afternoon.

Charles said he signed with Jacksonville for a "potential shot at the Super Bowl."

"That's why I still kept my options open, because I really wanted to win a championship," Charles said. "I was excited to have this opportunity come open, having a defense like this and having a running game and having [Blake] Bortles at quarterback.

"I was excited they would allow me to come and give me a chance. I'm happy that it worked out."

Charles (5-feet-11, 199 pounds), originally a third-round selection by Kansas City in the 2008 NFL Draft, has rushed for 7,556 yards and 44 touchdowns in 10 NFL seasons. He was a Pro Bowl selection following the 2010 and 2012-2014 seasons for Kansas City, and his 5.4-yards-per-carry average is the highest in NFL history for players with 1,000 or more carries. He was an Associated Press first-team All-Pro selection following in 2010 and 2013.

Charles, 31, who has rushed for more than 1,000 yards in five of 10 seasons, played in just eight games on 2015 and 2016 because of a torn anterior cruciate ligament sustained in Week 5 in 2015 and a meniscus issue midway through the 2016 season. He rushed for 296 yards on 69 carries in 14 games as a reserve for Denver last season.

"I want to come in here and make my own history," Charles said. "I want to start a new history. Everybody says, 'He's old right now.' I want to start something new. … I want to do something special for the Jaguars. I hope we can go all the way. That's why I'm here. I'm excited. …

"I have a lot [left]. I have to prove a lot. Opportunities like this don't come all the time. I'm excited. I'm here for a reason. I feel like it's God's plan. He made me wait this long. I could have done other things. I could have retired, but God kept this option open for me. It's God's plan."

Williams (6-1, 229), originally a seventh-round selection by Denver in the 2018 NFL Draft, spent the first five weeks of the season on Denver's practice squad. He played collegiately at Arkansas and South Carolina, rushing 304 times for 1,450 yards and 13 touchdowns.

Grinnage (6-5, 265), spent the entire 2017 season and the first five weeks of the 2018 season on Jacksonville's practice squad. He originally signed as an undrafted rookie with Green Bay shortly after the 2016 NFL Draft.

The Jaguars on Tuesday also officially placed tight end Austin Seferian-Jenkins and running back Corey Grant on their reserve/injured list. The team released running back Brandon Wilds.

Jaguars Head Coach Doug Marrone on Monday said while Grant is expected to miss the rest of the season, Seferian-Jenkins could return later in the season.

A team can designate two players per season to return from injured reserve. A player so designated can return to practice six game weeks after being placed on IR and can play eight games after being placed on IR. Seferian-Jenkins therefore could play Week 15 versus Washington.
