The Jaguars blew out the Indianapolis Colts during their Week 7 matchup earlier this year. Now set for a rematch in Week 13, Jaguars head coach Doug Marrone isn't taking the divisional rivals lightly.

"Like I've said before, I've got to get this team ready to play this Sunday and I've got to do a good job during the week," Marrone said Wednesday.

The Jaguars dominated the Colts in every phase during the 27-0 win in October. The offense produced three touchdowns, the defense tallied 10 sacks and special teams had one of its better performances of the season.

Marrone said the Colts have played better since the shutout. Indianapolis has been in a lot of tight games but has yet to find a way to win consistently.

"I think they are playing extremely hard," Marrone said. "The quarterback is doing a nice job, they're getting people open, they've got some weapons on that side of the ball, special teams the same way so, we've got to concentrate on getting ourselves ready."

Colts quarterback Jacoby Brissett was manhandled by the Jaguars' pass rush in their last battle. Marrone said the second-year player can hurt opposing defenses if he has time to throw.

"He's not throwing interceptions now," Marrone said.

"You're not seeing someone back there doing that, he's going through his reads. He's someone - from what I see - if you give him time and he stays in the rhythm, he can make all the throws. He's a very good throwing quarterback but he's also got the mobility to get out of the way and extend plays. What I see is when it's clean, he does a heck of a job."

Omameh, Parnell take part in first practice of Week 13

The Jaguars' starting offensive line may be intact when the team hosts the Colts at EverBank Field this weekend.

Starting left guard Patrick Omameh (calf) and right tackle Jermey Parnell (knee) participated in a limited capacity at practice to start Week 13.

Parnell has missed the last three games, while Omameh has been sidelined for the two consecutive contests. The duo has been replaced by swing tackle Josh Wells and guard Chris Reed in recent weeks.

Their return to practice early in the week is a good sign for the Jaguars. If the pair of linemen can gradually become more involved in practice over the next few days, their chances of playing on Sunday should be relatively high.

While Omameh and Parnell were back, the Jaguars were still without two starters at practice Wednesday.

Wide receiver Allen Hurns (ankle) and linebacker Telvin Smith (concussion) were sidelined due to injuries.

Quarterback Blake Bortles (wrist), cornerback Jalen Ramsey (ankle), wide receiver Marqise Lee (knee), running back Leonard Fournette (ankle), safety Tashaun Gipson (knee) and linebackers Donald Payne (hamstring) and Lerentee McCray (hamstring) also appeared on the team's injury report.

More News and Notes

- The Jaguars have announced that the team will wear teal again this season.

Jacksonville will wear the alternate teal jerseys in Week 14 against the Seattle Seahawks. The game will take place at EverBank Field at 4:25 p.m. on December 10.

- Marrone said he is confident in rookie linebacker Blair Brown if the team needs to replace Smith in the lineup. The head coach said Brown has improved throughout the season.

- Veteran running back Chris Ivory has been struggling since the bye week. He has been given just 16 snaps over the last three games. During that stretch, Ivory has produced -4 yards and a fumble on nine total touches.

Marrone put some of the blame for Ivory's woes on the offensive line's inability to open up holes in the defense.

- Marrone said he has seen cornerback Aaron Colvin elevate his play in recent weeks. He is happy with his production on the season.
