Hepburn (knee) didn't play in Thursday's 99-90 Summer League win against the Heat.
Hepburn also sat out of Monday's matchup due to a knee injury, so it appears the Raptors are taking it easy with the 23-year-old guard, especially after he underwent surgery for a torn meniscus in January. It's unknown if he'll be cleared to take the court over the weekend before Summer League winds down.
