Aircraft X a A330 was on the KEPEC arrival into LAS.  He checked on with speeds deleted from the Center.  I had to slow him to put him behind another arrival.  Aircraft Y was behind the Airbus by at least 11 miles.  Aircraft Y did not check in.  I reached out and they responded with they had an upset.  I asked if they were recovered and they said yes.  I slowed them to 230 kts.  Then Aircraft Y stated they had a crew member down.  I gave them a vector to get them in ASAP and told the FLM.  I handed off Aircraft Y to the final controller.I checked the replay and had 9 miles between the Heavy and Aircraft Y.  Also Aircraft Y was about 1;000 feet above the Airbus.I saw that the Center was deleting the speeds on the arrivals.  I should have reached out to them to have them stop doing that.  I thought I was safe with 9 miles with a heavy Airbus in front of the B737.
