Clemson coach Dabo Swinney announced Gore's condition after practice. The Tigers (2-2, 1-1 Atlantic Coast Conference) face North Carolina State (4-1, 0-1) on Saturday.
Gore started the Clemson's first three games. He was a backup at tackle last week in a 50-35 victory over North Carolina. Gore was listed as backup to Clemson's left and right tackle positions against the Wolfpack. He has averaged 47 snaps a game so far this season.
Gore's absence further weakens Clemson's depth on the offensive line. The Tigers had lost Patrick DeStefano and Gifford Timothy to career-ending injuries before the season. Then Shaq Anthony transferred in late August.
