The undefeated British heavyweight, Joshua, now holds the IBF, WBA and WBO boxing heavyweight titles. Hearn is understood to be keen on a Joshua versus Miller encounter, and the Brooklyn-born heavyweight could well be Joshua's next opponent, especially if the Briton takes a fight this summer.
As of March 13, Parker is at +600 to win the fight, and Joshua has odds of +225 to win in rounds four to six with Betway.
Wilder has called out Joshua on multiple occasions, and during the post-fight interview on Saturday night, Joshua returned the favor by screaming "Wilder, let's go baby, let's go!"
Parker's best rounds were the first two and possibly the fifth, but he looked the most unsafe when he was tagged. When he did attack, Parker looked threatening, but the continued efforts of referee Giuseppe Quartarone to get in the way, and Joshua's defensive expertise, contrived to stymie that.
The traditional staredown passed without drama, the pair shaking hands (prompted by Joshua), and Parker saying "all the best" to his opponent at the end of a short conversation. There's always been talk of what's happening next and I've said this is my main focus.
"If they (Wilder's management) stepped up and were actually serious about the fight, and serious about a deal we are more than fair to offer them, it could happen next". "We will back again stronger and I'm happy I went the 12 rounds".
"But they are so erratic and unpredictable, I don't know what to believe".
"I've been running well, training well", said the 2012 Olympic champion, who has a 20-0 record with all his fights won by knockout. "I said this would be about boxing finesse". That particular matchup is slated to be one of the biggest heavyweight fights of all time, and could very well take place sometime next year in Joshua's home of England. Back in May 2016, Takam fought Joseph Parker in New Zealand and lost by unanimous decision. He is the mandatory WBO challenger and would undoubtedly be viewed as a risky opponent, but any fight would potentially lack the pulling power of a Wilder showdown.
The 26-year-old New Zealander, who had been led into the ring by Samoan chiefs under a barrage of strobe lights before Joshua walked in to the sound of "Paid in Full" and "Another One Bites the Dust", was gracious in defeat. Beyond Wilder and Povetkin, the most unsafe tests are rematches against Parker and British rival Dillian Whyte.
