Inboudn play with 2.8 seconds left

[tjlref]

Suppose in this situation A1 passes to A2, who is still OOB, and A2 fumbles the ball and it rolls inbounds. Is this considered a pass inbounds or could A2 retrieve the ball, step back OOB and pass the ball inbounds to another player, as long as 5 seconds has not elapsed?


In another situation, if A2 did not catch the ball and it went beyond the sideline and went into the bench area or the stands, what now??
