Knoxville heads to the Southeast Polk Volleyball Invitational today.  The Panthers are 8-7 on the season after Tuesday’s loss to Pella Christian.  Coach Eric Fee says Tuesday night the Eagles got Knoxville out of position several times.  The Panthers have a chance to play Pella Christian again today since both teams are in the same pool.  Joining the Panthers and Eagles will be Grandview Park Baptist and Des Moines Roosevelt.
