Jets RB Elijah McGuire fractured his foot during practice on Friday, coach Todd Bowles said on Saturday.
McGuire may need surgery to stabilize his foot, a source told SNY's Ralph Vacchiano, and it is not clear when he could return.
Running backs Alfred Morris and Orleans Darkwa visited the Jets on Saturday.
McGuire, 24, rushed for 315 yards in 16 games during his rookie campaign last year. He averaged 3.6 yards per carry and scored two touchdowns -- one rushing and one receiving. He caught 17 passes for 177 yards.
