Jets coach Robert Saleh said after Sunday's game that "the initial diagnosis was not good." The Jets defeated the Denver Broncos 16-9 to improve to 5-2.
However, Hall left in the second quarter after landing awkwardly while getting tackled. He had already scored on a 62-yard touchdown run in the first quarter. He finished with 72 yards rushing before leaving.
Hall took to social media postgame but didn't discuss his injury.
"Resilient," he wrote. "Through all the trials and tribulations JETS WIN!!!!"
Jets right tackle Alijah Vera-Tucker (elbow) and wide receiver Corey Davis (knee) also left Sunday's game with injuries.
