JACKSONVILLE – The Jaguars will have a change at right tackle Sunday.
They're uncertain at kicker entering the weekend, too.
Jermey Parnell, a starting right tackle in the first 13 games of the season, on Friday was ruled out of the Jaguars' game against the Washington Redskins Sunday. Parnell has been hampered by a knee injury much of the season.
Also Friday, the Jaguars signed veteran kicker Kai Forbath.
Jaguars kicker Josh Lambo, one of the NFL's most consistent kickers this season, sustained a groin injury Thursday – with Head Coach Doug Marrone saying on Friday that Lambo's status for Sunday is uncertain.
"We don't really know how it's going to go," Marrone said of Lambo's status for Sunday's 1 p.m. game at TIAA Bank Field in Jacksonville. "It's not a lot of time between now and Sunday for an injury like that. We're going to take it day-by-day, probably up until game time."
The Jaguars placed rookie linebacker Leon Jacobs (quadricep) on injured reserve to make room for Forbath on the roster.
Forbath, who originally signed as an undrafted free agent with Dallas in 2011, played for the Redskins from 2012-2015 and with the Minnesota Vikings from 2016-2017. He has made 116 of 135 career field goals and 169 of 180 extra-point attempts.
Lambo has made 19 of 21 field-goal attempts this season and 19 of 20 extra points.
Parnell's injury means the Jaguars could start Josh Wells at right tackle Sunday and would mean yet another change on an offensive line beset by injuries in the second half of the season.
Wells, who started at left tackle in Weeks 3-5, has spent the last eight games on injured reserve with a groin injury sustained in a Week 5 loss at Kansas City. He is eligible to come off injured reserve this week, and Marrone said that move likely will be made Friday.
"He's been practicing and really done a nice job," Marrone said of Wells. "He was playing probably the best he's played prior to being injured. He's come back this week and he's shown the same type of practice mentality and the same type of production. We've got to make a move today – which we're going to meet about to see what's the best move for our team – to bring him up."
With Parnell out, the Jaguars' offensive line on Sunday will feature just one player who started Week 1: right guard A.J. Cann. The three other Week 1 starters – left tackle Cam Robinson (knee), left guard Andrew Norwell (ankle) and center Brandon Linder (knee) – are on injured reserve.
"It's the nature of the beast," Marrone said. "It's unfortunate. I look at it as guys have worked really hard and guys who are really trying and they have injuries. They have injuries. There's nothing you can do about it. It's part of this game."
Parnell was one of three Jaguars players ruled out Friday, with rookie wide receiver DJ Chark Jr. ruled out of a fourth consecutive game with a quadriceps injury and offensive lineman Josh Walker ruled out of a fifth consecutive game with a foot injury.
Defensive end Lerentee McCray (illness) is listed as questionable entering the weekend after not practicing Friday. Safety Cody Davis (illness), tight end James O'Shaughnessy (ankle) and nose tackle Abry Jones (shin) were removed from the injury report after practicing Friday.
