I'm not sure whether the captain, L.S., was 'suspended' but it does appear in the UAL scheduling computer that his next trip was dropped.
And there are several ways you can be removed from flying by the feds, they can pull your license, take your medical or put you in TSA 'no fly' status until you prove fit to fly. I've seen all of the above in recent years after various incidents.
The fact that the captain continued on duty after the divert reminds me of what the pilots of the 89th MAW, the operators of Air Force One, are told: you are allowed one mistake and you won't be fired until you get home from the trip!
