In the first game of the 2017–18 season, Kimble scored 10 points against Toledo but re-injured his foot, forcing him to miss the remainder of the season.[5] Kimble averaged 15.6 points, 3.6 rebounds and 2.8 assists per game as a redshirt junior, but struggled with his three-point shooting, hitting 29 percent of his attempts.[6] He missed 10 games with a hand injury but earned Second Team All-Philadelphia Big 5 honors.[3] The team finished 14–19, and Kimble opted to transfer for his final season of eligibility after St. Joseph's fired coach Phil Martelli.[7] After receiving interest from several schools, Kimble transferred to Louisville due to his familiarity with assistant coach Luke Murray and the success of graduate transfer Christen Cunningham the previous season.
