JACKSONVILLE – The Jaguars received unexpected news Wednesday.

It's news that doesn't help the team's secondary depth.

Josh Robinson, an eight-year veteran who had played a role on special teams and as a reserve cornerback, on Wednesday morning informed Jaguars Head Coach Doug Marrone he is retiring from the NFL. Marrone informed the media of the news Wednesday morning.

"He had been awesome for us; no issues, no problems," Marrone said as the Jaguars (4-4) began preparing to play the Houston Texans (5-3) at Wembley Stadium in London Sunday at 9:30 a.m.

Robinson, 28, previously played with Minnesota, Tampa Bay and New Orleans. He signed with the Jaguars shortly before 2019 Training Camp and had been active in all eight games this season, registering two-and-half tackles on special teams.

"He's obviously put some thought into it," Marrone said. "I have all the respect in the world for him – tough kid, practiced hard, prepared like a pro … nothing but the best for him. We're always here for him. Appreciate him."

Robinson's retirement leaves the Jaguars with five cornerbacks on the roster.

Tre Herndon has started at corner the last six games, with A.J. Bouye starting all eight games this season and D.J. Hayden playing nickel corner in all eight games. The Jaguars signed Tae Hayes from the practice squad Tuesday, with Breon Borders also on the roster. The Jaguars traded cornerback Jalen Ramsey to the Los Angeles Rams earlier this month.

Hayden, one of the Jaguars' best defensive players through eight games, is expected to miss practice Wednesday with a neck/shoulder injury sustained in a victory over the New York Jets Sunday. Marrone said the team will "wait and see" about Hayden's status for Sunday.

"We're going to take it day by day, and we have all the way up until game time," Hayden said. "I just think it's a matter of resting it and everything calming down. If it's calmed down, he's ready to go. He'll be listed as questionable and we'll see where he is."

In other injury news:

*Kicker Josh Lambo is expected to miss practice Wednesday with a groin injury. Marrone said he expects Lambo to play Sunday, but said the team may "back ourselves up and bring some guys in" this week. "We leave and go to London [Thursday], so we just want to make sure beforehand," Marrone said. "Once you go, you're there. It's not like you can just pick somebody up on Friday to come on in and go play."

*Wide receiver Dede Westbrook is expected to practice limited Wednesday after missing the second half of the Jets game with a neck/shoulder injury through which he has played in recent weeks. Wide receiver DJ Chark Jr. (quad) is expected to practice limited Wednesday.

Weak-side linebacker Quincy Williams (hamstring) is expected to miss practice and starting strong-side linebacker Leon Jacobs (hamstring) also is expected to miss practice.
