CHARLOTTE – Left guard Travelle Wharton, who hasn't played in a month because of a toe injury, joined the lengthy list of Panthers on injured reserve Tuesday.
The team also placed defensive end Everette Brown (wrist) and linebacker Jason Williams (knee) on IR, making official what head coach John Fox indicated on Monday would happen.
The Panthers now have 13 players on IR, one shy of the team record established in 2004.
Carolina filled two of its three vacant spots on the 53-man roster by signing defensive tackle Corvey Irvin and cornerback R.J. Stanford from the practice squad. The Panthers then filled one of two openings on the practice squad by signing defensive tackle Tommie Duhart, an undrafted rookie from Valdosta State.
Wharton, who joins starting right tackle Jeff Otah on IR, suffered his injury at Tampa Bay on Nov. 14 and hadn't practiced since. Mackenzy Bernadeau has been starting in his place.
Wharton had started 38 consecutive games and 55 of Carolina's last 57 games before the toe injury. A third-round draft pick by the Panthers in 2004 out of the University of South Carolina, Wharton also was on IR in 2006, when he suffered a knee injury in the season opener.
Irvin (6-3, 302 pounds), a third-round draft pick in 2009, will get his first look on the active roster. The University of Georgia product spent his rookie year on IR after suffering a knee injury in the final preseason game.
The Panthers waived Irvin in the final roster cutdown this year but signed him to the practice squad two days later, where he's remained until now.
Stanford (5-10, 183 pounds) also was waived in the Panthers' final roster cut and then added to the practice squad. The University of Utah product was picked in the seventh round of the 2010 NFL Draft.
With the addition of Stanford, all 10 of the rookies drafted by Carolina in 2010 have been on the 53-man roster at some point this season. Nine are currently on it (quarterback Tony Pike is on IR), along with undrafted rookie defensive tackle Andre Neblett.
The Panthers still have on opening on the 53-man roster and one on the eight-man practice squad.
