Hayes (knee) has been ruled out for Friday's game against Denver, Dave McMenamin of ESPN.com reports.
Hayes will miss his fourth consecutive contest due to a right knee contusion. His next chance to play will come Sunday against the Suns. Christian Koloko and Alex Len are candidates for an uptick in minutes, especially if Dorian Finney-Smith (ankle) and/or Trey Jemison (illness) are ruled out.
