Never want to see anyone get hurt but this is the list I saw online a few times circulating around.

LB Buddha Al-Uqdah - OUT
LB Jacob Manu - Questionable 
DB Dyson McCutcgeon - Questionable 
WR Omari Evans - Questionable

Also..

DB Tacario Davis is unknown to play this weekend

Hard to say who will/won't play outside of the LB that is out but it was my understanding UW's defense wasn't the greatest already so this may be interesting.
