Even if green is injured, I don't think Lav comes in for him yet.
As others have said, it's his 3rd game back, first full game but ....
ATM all of our small forwards in the seniors are running through the midfield for periods of the game, they are applying pressure in our forward half.
I just can't see lav doing either of those 2 important things ATM. He won't get the luxury of solely being able to play in the fwd 50, and he definately won't be the no.1 main target like he was on the weekend.
I'd say work on his match fitness, get the midfield time up and work on his defensive pressure and he could and should be ready to play seniors in 2-3 weeks.
