Caggiula was put on waivers Saturday.
Caggiula inked a two-year, two-way contract with the Oilers on July 1. He played in four NHL games with the Penguins last season but failed to hit the scoresheet. The 29-year-old had 22 goals and 53 points in 65 AHL games with Wilkes-Barre/Scranton last season.
