Brock Lesnar is expected to be off WWE television up until the build to SummerSlam, which makes that around 4 months.
The sheriff of Suplex City, Bitch, was “suspended indefinitely” on Raw after he destroyed the Raw announce team of Michael Cole, JBL, and Booker T, flipping the broadcast booth on JBL and Booker and then F5’ing Michael Cole out of his shoe. He then F5’ed the cameraman as an exclamation point. Stephanie McMahon suspended Brock and then announced she was fining him as well.
The suspension is obviously a storyline to explain Lesnar’s time away from WWE television due to the way his contract is drawn up. Lesnar only has a set of dates to work per year and is brought in for the big and important events.
