Dallas Mavericks' All-Star guard Luka Doncic moved to dispel speculation about his long-term future with the franchise, insisting he is happy where he is.

Reports emerged suggesting Doncic could evaluate his future with the Mavericks after they missed the 2022-23 playoffs with their first losing season (38-44) since the Slovenian's rookie year with Dallas.

That came despite the March trade for Kyrie Irving in an effort to make them championship contenders, yet they struggled with a miserable 7-18 run end to the season.

Doncic previously acknowledged publicly that he has been frustrated by their slide, but claimed that was natural given their poor results.

The guard signed a $207million contract extension in August 2021 keeping him tied with the Mavs until 2027, but players have opted out of long-term deals in the past.

Dallas owner Mark Cuban said this week that the Mavs had to "earn" Doncic's loyalty for him to spend his entire career with them.

The Slovenian cooled the concerns after the Mavs' season ended with a 138-117 loss to the San Antonio Spurs.

"I'm happy here, so there's nothing to worry [about]," Doncic told reporters.

"I saw the report. I don’t know who, somebody said I was going to request a trade. It was funny as I didn’t know it was true. I didn’t say it."

Doncic said he hoped for offseason personnel changes to bolster the Mavs line-up, although he declined to comment on any specific player targets. He also endorsed Irving as his backcourt partner despite their struggles since his arrival.

"Something's got to change, for sure," Doncic said. "I mean, last year we went to Western Conference finals. We were having fun. I always talk about the chemistry we had. It was great. But something's got to change for sure."

On Irving, Doncic added: "I think it's a great fit. Obviously people are going to say no [and] look at the results we are having, but like I said, chemistry and relationships takes time. I wish he can still be here."

The Mavs are under NBA investigation after resting a series of key players for their penultimate game against the Chicago Bulls which they lost 115-112, ending their hopes of making the play-in tournament.

Finishing 11th in the West and missing the play-in meant the Mavs finished with the 10th-best lottery odds, which is important as Dallas owe the New York Knicks a top-10-protected pick, prompting the investigation.

"I didn't like that decision," Doncic said. "That's it."
