Human Factors; Procedure
While on a left downwind; TUS Approach cleared us for the visual approach to Runway 11L. While approaching POCIB from the north at 4;600 feet; TUS Tower advised us of a low altitude alert and asked us to check our altitude.  We were VMC; clear of terrain visually; and did not receive any GPWS alerts. We reported the runway in sight and continued the approach and landing uneventfully.
A widebody First Officer reported ATC advised them of a low altitude alert on left downwind at TUS. No GPWS; terrain in sight; so approach was continued to a normal landing.
