Essendon's previously suspended players hit the training track in an official capacity for the first time in 10 months on Monday morning.

Nine of the 10 players who were banned for the entire 2016 season because of the supplements saga joined the first to fourth-year players at Essendon's training hub in Tullamarine.

Jobe Watson - sporting a backwards hat, bright yellow boots and a broad smile - took part in the session, as did Dyson Heppell, who was looking particularly lean.
