Not necessarily. They are mathematically eliminated from the top 2 spots. Most likely eliminated from the 3rd spot.
So that leaves 4-8 available. They might be ok if they can take 2 of 3 from Purdue and one from Illinois.
#9 Minnesota is one game behind Nebraska. They have a series at Iowa and host a series with Michigan St.
It looks like it'll be between Minnesota and Nebraska for the 8th spot. Nebraska won the series with them (2-1) so they'd get a head-to-head in event of a tie breaker.
