CHARLOTTE — Defensive end Yetur Gross-Matos on Thursday missed a second straight practice with an ankle injury.

The second-round pick played 17 snaps in Sunday's win over the Falcons. He went off the field gingerly in the third quarter before returning in the fourth. But late in the period, he was declared out.

Head coach Matt Rhule had no update on Gross-Matos on Thursday.

Defensive end Brian Burns (concussion) was a limited participant in Thursday's practice, an upgrade after not participating on Wednesday. He was in a green jersey for the day's session, signifying no contact, as he works his way through the concussion protocol.

"He was allowed to do some things today," Rhule said. "He looked good, would certainly love to have him (against the Bears)."

Wide receiver Curtis Samuel (knee) and cornerback Donte Jackson (toe) were both limited participants again on Thursday. Rhule confirmed Jackson's toe injury will be something he just has to fight through this year.

Cornerback Eli Apple (hamstring) was a full participant. If he's able to play on Sunday, it will be to provide depth behind Jackson, Rasul Douglas, and Troy Pride Jr.

Two offensive linemen did not participate: Michael Schofield (not injury related) and Tyler Larsen (illness).

While the move has not yet been made, Rhule said he anticipates Keith Kirkwood will come off injured reserve to the 53-man roster this week. The Panthers placed defensive tackle Kawann Short (shoulder) on injured reserve Thursday, opening a spot on the active roster. Rhule said Short's surgery is scheduled for next week.
