Lewis tore a ligament in his elbow and had surgery in 2017. He hasn't had reports of elbow issues since, and we don’t have evidence to indicate that this will negatively impact his playing career. In 2018, he tore the ACL in his knee, which does present concern. A recent study of 110 NFL Combine participants with a history of prior ACL surgery found that these players averaged ~3 fewer games started and ~3 fewer games played in each of their first 2 seasons in the NFL compared to their peers. Additionally, they participated in ~25% fewer plays. Multiple studies in NFL players have associated ACL injury history with decreased career lengths, though mixed results have been reported regarding the effect on player productivity. The ultimate impact of the injury is affected by the degree of damage to other structures in the knee (meniscus and cartilage, which serve protective roles in the joint) that can be hurt at the time of the ACL tear. If accurate, reports that multiple teams (reportedly nearly half) have failed him on his physical increases our suspicion that he did sustain injury to these structures, which would worsen his outlook. However, such reports are also very difficult to trust, with NFL executives often looking to manipulate the draft stock of targeted players. Regardless of whether or not this is the case, medical evidence already leads us to a fair amount of concern for his long-term durability.
