Atom's red card was for the violent conduct after the challenge (grabbing the neck area of the West Ham player who came over to "intervene").
Three match ban, he misses the remainder of the "regular" season.
Don't worry - no first team fixture for 16 days, no U-21s fixture after today for 24 days and after tomorrow, no U-18s fixture for 21 days!
You'll have forgotten who Brighton and Hove Albion are by the time we start playing again.
