Arizona Cardinals linebacker Sean Weatherspoon left Saturday's practice with a hamstring injury, according to Kent Somers of AZCentral.

The severity of the injury is unknown.

Weatherspoon has struggled with significant injuries throughout his career, and is coming off a torn Achilles in 2014. He signed a one-year contract with the Cardinals in March after spending the first four years of his career with the Atlanta Falcons.

Head coach Bruce Arians will address the media before afternoon practice on Sunday and may be able to report on the severity of the injury at that time.
