Star Essendon midfielders Jobe Watson and key position player Adam McPhee could both play on Friday night against Collingwood.

"(Watson)'s recovered pretty well, pretty quickly, so we'll give him a test this morning and we'll weigh it up after that," assistant coach Scott Camporeale said.

"(McPhee)'s got a pretty good record against (Travis) Cloke when we've played previously - he trained fully on Tuesday and he'll have another fitness test today as well, just to make sure he's cherry ripe, ready to go."
