The #1-ranked Clemson Tigers, champions of the Atlantic Coast Conference, faced the #4-ranked Alabama Crimson Tide, co-champions of the SEC West Division (along with Auburn who won head-to-head over Alabama.) This was the third consecutive year in which Clemson and Alabama met in the CFPs, though the previous two meetings were in the CFP Championship Game.
Notes
January 1, 2018 – The Rose Bowl in Pasadena hosted the other semi-final game.
This was Alabama's first Sugar Bowl win of the Nick Saban era. This was also their first win in a Sugar bowl since 1993 against Miami. The Tide had lost games in the 2008–2009, 2013–2014, and 2014–2015 football/bowl seasons. This was also the first win for the Southeastern Conference in the Sugar Bowl since 2010 (Ole Miss has to vacate a win over Oklahoma State), including losses to Louisville, Oklahoma (twice) and Ohio State (twice).
Game summary
The Crimson Tide immediately took a 10–3 lead at halftime. Alex Spence was the only player to score for the Clemson Tigers with just two field goals. Alabama's defense was a huge factor in the game holding the Tigers to only six points. This matchup was a rematch of the 2017 College Football Playoff National Championship in which the Tigers won with quarterbackDeshaun Watson leading the team as the game's MVP. The Tigers were not able to perform without Watson and with Kelly Bryant.
