Two men enter

As Tsunade leaves a gate opens up and Sakura quickly hides behind a tree, she sees two large men walk in, both dressed in sand ninja armour, one has a bag on his back, which likely has some of the supplies Tsunade mentioned earlier.

The two men walk away from the gate as it closes and start to head into the arena, they didn't seem to be looking for Sakura, in fact unknown to her their orders were to simply cross the arena to the gates on the other side.
