Hayes is listed as questionable for Monday's game against the Grizzlies due to right shoulder soreness, Shreyas Laddha of The Salt Lake Tribune reports.
Hayes could be held out of the second leg of this back-to-back set after posting nine points, five rebounds, a steal and an assist in 19 minutes during Sunday's loss to the Lakers. If the big man joins Jusuf Nurkic (foot) on the inactive list, Kyle Filipowski and Mo Bamba would be candidates to see increased minutes off the bench.
