Detroit Lions second-year running back Sione Vaki left Monday’s training camp practice early with what team officials have described as a leg injury.
The injury occurred during position drills early in the session. Vaki was seen receiving attention from team trainers on the sideline. They worked to stretch him out, but shortly after, head coach Dan Campbell walked over to check on the situation. Moments later, Vaki was seen walking toward the back, away from the field.
At this time, the team hasn’t provided any further details, only saying that the 2024 fourth-round pick is undergoing evaluation.
This summer is a crucial window for Vaki. He’s competing to lock down the RB3 spot behind the dynamic duo of Jahmyr Gibbs and David Montgomery. After switching from safety to full-time running back as a rookie, Vaki is now expected to show real growth and establish himself as a contributor in Detroit’s backfield.
Last season, the 23-year-old appeared in 16 games, recording six carries for 14 yards and three receptions for 37 yards. Though limited on offense, he made a significant impact on special teams, where his toughness and instincts from playing safety helped him stand out. His efforts earned him a spot on the PFWA’s All-Rookie Team as a special teamer.
With four preseason games ahead and a strong likelihood that neither Gibbs nor Montgomery will suit up for them, Vaki has a real opportunity to get meaningful reps — if healthy. The coming days will be critical as the Lions assess the severity of his injury and his availability moving forward.
