History[]
By 2372, he reached the rank of lieutenant commander and was assigned to the USS Enterprise-E as a beta shift watch officer. During one of his shifts, Doctor Beverly Crusher contacted the bridge to ask him if any of his bridge officers had any trouble with sleeping. As they were talking, tactical officer Lieutenant Sanders started to fall asleep and was sent down to sickbay. (TNG - Slings and Arrows eBook: That Sleep of Death)
