DIG vs REN, REN vs Tip

So, theoretically speaking, if DIG loses both their games this weekend and Ren loses vs Echo Fox tomorrow, will DIG and Ren play a tie breaker for 9th? OR if REN wins both games this weekend, and TIP loses tomorrow, will they play a tiebreaker for 8th? REN has a 1-1 record against both these teams. Just wondering if anyone knew

EDIT: Better yet, what if REN and DIG win tomorrow, and TIP loses, creating a 3-way tie for 8th. What happens in that scenario?
