Deadspin gives a pretty good overview. Essentially Portnoy published a photo of Brady's naked son and joked about the size of his penis. WEEI then used the backlash to drive its programming all day with Glenn Ordway taking particular delight in it. Then Jason Wolfe banned Portnoy, who was a regular contributor at the time, from WEEI's airwaves.

To expand, WEEI went through (is still going through?) an extraordinarily tone-deaf and desperate attempt to cop the T&R "shock jock"/pottymouth gestalt, back when they were still trying to claim they had better overall morning ratings. Portnoy and Minihane were, I think, part of that younger-demographic outreach attempt, as was the (now abandoned) moratorium on talking politics.
EEI of course colossally screwed the pooch in this attempt. Instead of mirroring T&R's juvenile, funny, self-effacing routine, D&C&M took their baser instincts to new depths of meanness, sexism, voyeuristic homophobia and dirty-old-man-ness, and generally created an even uglier and more off-putting version of their angry white men persona. Minihane, instead of taking the conversation in a younger, hipper, more-inclusive direction, got himself repeatedly suspended, including for doubling down on a week-long bit that involved calling Erin Andrews a "gutless bitch", telling her to drop dead, and saying that she would be a waitress if she was 15 pounds heavier. D&C, deprived of their ability to discuss politics, instead revelled in using every LGBT news item, no matter how trivial, as a springboard for their own vivid and imaginative depictions of what the mechanics of LGBT sexuality must really be like.
Barstool Sports, by this point in time, was more than halfway to being a porn/shock website. One of those armpit-of-the-internet click-bait-y sites that specializes in creepy nudes, where paparazzi/tabloid journalism standards are something to aspire to, and 4chan/reddit are kind of the baseline. Portnoy brought a similar level of sophistication to his appearances on D&C, which became frequent enough that it looked for a minute like he might be almost under consideration for a fourth chair slot, or maybe even the third. His ability to bring the latest dregs of the internet as discussion topics, was like bringing a 1,000-gallon barrel of personal lubricant to D&C&M's panel of prurient self-indulgence.
So by the time Portnoy's website and on-air persona were literally using the genitals of a toddler as a headline discussion topic, and publishing pictures of same, when said toddler happened to be the child of the show's most-famous guest and primary ratings draw, it was a kind of culmination of a strategy that they had been desperately and wrongly pursuing for some months. Neither the show nor the station seemed to notice anything was wrong until it was pointed out in the national media that they were, you know, actually talking about pictures of a child's genitals. In detail. And directing listeners to where to find these remarkable pictures online, so they could call in and join the fun on-air.
Then, of course, the top minds at EEI banned Portnoy, and once again re-jiggered the rules of topicality for the morning show. I think there was a lot of golf chat for a while. That may have been about the time that Minihane decided to go hard after the competition, by throwing down the now-legendary "Sports Debate" gauntlet.
