SPARTANBURG, S.C. – The Panthers released their first "unofficial" depth chart ahead of Thursday night's preseason opener at the Buffalo Bills.

While keeping in mind that the depth chart is very much subject to change as the preseason continues, here's a rundown of the notable items:

- Amini Silatolu is listed as the starting left guard – no surprise considering he's been first up at that spot throughout camp. Jeremiah Sirles is listed as the primary backup at both guard spots and at right tackle to Taylor Moton, who is now the starter with Daryl Williams sidelined by a knee injury. Undrafted rookie Brendan Mahon has had a strong camp, and he's listed as the third-string left guard.

- The wide receivers are organized in two columns, which oversimplifies those roles. That said, the first pair is Devin Funchess and Torrey Smith, followed by Jarius Wright and first-round pick DJ Moore, followed by Damiere Byrd and Curtis Samuel.

- Behind Cam Newton, the quarterbacks are ordered Garrett Gilbert, Taylor Heinicke and Kyle Allen.

- Rookie defensive end Marquis Haynes has impressed, and he's slotted behind starting right defensive end Mario Addison. Daeshon Hall, working his way back after an injury-plagued rookie season, is listed after Haynes.

- Kevon Seymour is listed as the starting cornerback opposite James Bradberry. Rookie Donte Jackson, who is competing for that starting spot and making a strong case, is listed behind Seymour.

- Da'Norris Searcy is listed as the starting strong safety, with Colin Jones backing him up. Rookie safety Rashaan Gaulden is slotted as the backup to free safety Mike Adams.
