The Panthers aren’t saying it, but there’s a possibility that they will be without their sack leader for this weekend’s game against the Seattle Seahawks.

Mario Addison missed his second straight practice on Thursday due to a chest injury he suffered during last weekend’s loss to the Atlanta Falcons. He currently leads the Panthers in sacks with 9.5 on the season.

Interim head coach Perry Fewell said Addison not practicing is still a “precaution,” so that leaves some hope that he could play this Sunday.

If Addison cannot play against the Seahawks on Sunday, that will likely mean more playing time for rookies Brian Burns and Christian Miller. Despite battling a wrist injury throughout the season, Burns is tied with Bruce Irvin for second on the team with 5.5. However, Burns has registered just one sack since having surgery on his wrist during the Panthers’ bye week.

Left tackle Greg Little also missed practice once again as he is still dealing with the effects of an ankle injury he suffered against the New Orleans Saints back in Week 12. He has not played since suffering the injury and it appears he’s could miss his third consecutive game.

Marquis Haynes is still day-to-day with a knee injury he sustained against the Falcons as he left Mercedes-Benz Stadium last Sunday on crutches. Carolina signed linebacker Ramik Wilson this week after waiving wide receiver Greg Dortch on Tuesday afternoon. So Wilson could potentially be active on Sunday if Haynes cannot play.

There is some potentially good news in that Greg Olsen did practice for the second consecutive day on a limited basis. The tight end has been in the concussion protocol since suffering a hit to the head against the Redskins in Week 13. Olsen will have to complete a five-step process that including being passed by both the Panthers team doctor and an independent neurological before he can return to game action.
