The Steelers waived Watts on Tuesday, Teresa Varley of the team's official site reports.
After being waived by the Packers in training camp last year, Watts joined the Steelers' practice squad in September and signed a reserve/future contract with Pittsburgh in January. He was competing for a depth wide receiver role in training camp, but he only managed to record two catches for 14 yards across three preseason games. Assuming he goes unclaimed off waivers, Watts could be invited back to the Steelers on the practice squad roster.
