CLEMSON, S.C. (AP) — Clemson quarterback Trevor Lawrence, wearing a mask and standing on the sideline, watched his Notre Dame counterpart Ian Book rally the Fighting Irish to a dramatic victory last month. Lawrence is expected to play a major role in what happens in the rematch when the second-ranked Fighting Irish (10-0, 9-0 ACC; No. 2 CFP) take on No. 4 Clemson (9-1, 8-1; No. 3 CFP) in the ACC championship game on Saturday in Charlotte, North Carolina. ADVERTISEMENT Sidelined with COVID-19, Lawrence was a spectator in Notre Dame’s 47-40 double-overtime victory in November — Clemson’s lone loss this season. Lawrence traveled with the team to Indiana and gave advice to his backup, freshman DJ Uiagalelei, throughout the game.
