Last Saturday's cut-down date for the Jaguars wasn't the end of their roster moves for the season opener on Sunday against Kansas City.

After last week's final cut-down date, the Jaguars' front office went to work, mostly on one side of the ball.

Eight additional players were signed who had been cast off by other teams, and there was a clear pattern to the team's plans: six were offensive players, one plays on defense and the other special teams -- long snapper Matt Orzech, who steps right in to replace Matt Overton, who was cut.

Five of the new players were put on the active roster, and three play on offense: running backs Tyler Ervin and Devine Ozigbo and tight end Seth DeValve. The others added to the 53-man roster were Orzech and linebacker Austin Calitro.

Three were placed on the practice squad, all of them on offense: quarterback Chase Litton, wide receiver Keelan Doss and tackle Blake Hance.

Ervin and DeValve have the most NFL experience, both entering their fourth seasons. Ozigbo, Orzech, Doss and Hance are rookies and Litton is entering his second season.

"I think those guys will help us, no doubt," said offensive coordinator John DeFilippo of the players on his side of the ball.

But he did counsel patience about any roles they might play in Sunday's opening game against Kansas City, at TIAA Bank Field (1 p.m., CBS).

"To think that those guys are going to come in here and be a huge piece of what you're going to do after these guys [players who were already on the team] have been here six weeks? I think it's hard," DeFilippo said. "Will they play? Absolutely."

The key additions are Ervin and Ozigbo. With Alfred Blue on the Reserve/Injured-Designated to Return list, Leonard Fournette's only backup was rookie Ryquell Armstead.

Even adding Ervin doesn't really increase the experience factor that much. In three seasons with Houston and Baltimore, the former San Jose State player was primarily a punt and kickoff returner, and enters the season with only five career carries (for 15 yards). He does have 14 career receptions for 91 yards.

However, Ervin does have a decent track record on special teams. He was third in the AFC in punt return average as a rookie with Houston in 2016 (9.7).

And perhaps there were long memories in the Jags' front office. Ervin broke off a 57-yard punt return in 2016 against the Jaguars in the Texans' 24-21 victory at TIAA Bank Field.

He has a more important connection to the Jaguars: When Ervin was a freshman at San Jose State, DeFilippo was his offensive coordinator.

Ervin went on to break the school record for career all-purpose yardage (6,146) and returned three kickoffs and two punt for touchdowns.

"I've got a good feeling for what kind of guy he is. ... He's an awesome coach," Ervin said. "I'm glad to be here with him. He's a winner. He has high expectations, and I've got to go out and do the best I can. I'm ready to fill in where they need me."

Ozigbo, who was cut by New Orleans, led Nebraska with 1,082 yards and 12 touchdowns last season. He had 49 career receptions for 488 yards for the Cornhuskers.

Ozigbo is now the Jaguars' tallest running back at 6 feet 2 and gives away only 3 pounds to Fournette.

"I think I'm a pretty versatile back for my size,"Ozigbo said. "I can run routes, catch the ball and be kind of elusive , ut I think I bring some power if that's needed. I'm going to try to do everything great and let them figure out want they want out of me."

The Jaguars also filled some depth with DeValve, who caught 48 passes for 199 yards and four touchdowns with Cleveland from 2016-18. The Princeton graduate caught 33 of those passes for 395 yards in 2017.

With rookie Josh Oliver still listed as out for Sunday's game, the Jaguars needed another target at tight end to go with James O'Shaughnessy and Geoff Swaim.
