Dan Friedkin is interested in purchasing the Houston Rockets.

Friedkin's wealth primarily comes from owning Gulf States Toyota Distributors. Toyota already has the naming rights to the Rockets' arena.

“Over the years we have enjoyed a close partnership with the Rockets and Les(lie Alexander) through Toyota’s naming rights of the arena,” Friedkin told Fox 26 through a statement. “As a Rockets fan and Houstonian it would be exciting and a privilege to build on the storied legacy of NBA basketball in this city.”

Friedkin is worth approximately $8.4 billion.

Friedkin becomes the second billionaire to enter the race, after Houston native Tilman Fertitta announced his interest. 

In July, Les Alexander announced he intended to sell the Rockets.

NBA owners are expected to approve player-resting rules in September designed to cut back on teams sitting players for regular season games.

The rules will be in place by the start of the 2017-18 season, and there will be consequences for teams that do not adhere to them.

The move is designed to appease fans and the NBA's business partners.

“There is an expectation among partners that teams are going to act in appropriate ways, (and) find, as I said, that right balance between resting on one hand and obligations to fans and partners on the other,” NBA commissioner Adam Silver told reporters at his April news conference.

The NBA has outlined changes to their schedule in a memo to all 30 teams.

After a series of high-profile players didn't play in major matchups last season, the new schedule protects key national television matchups to make sure teams aren't playing on back-to-back nights. The schedule also hopefully reduces the risk of injury.

The NBA is moving up the start of the regular season by one week.

Some of the new improvements include:

• Eliminating stretches of four games in five days and 18 games in 30 days.

• Reduction of five games in seven nights to just 40 instances across (1.3 per team), down from last year when it was on the schedule 90 times (three per team).

• Reduction in number of back-to-backs to 14.9 per team, down from 16.3 per team. In all, 40 back-to-backs have been eliminated from last season.

• Reduction of single-game road trips by 17 percent.

• Reduction in single-game road trips over 2,000 miles by 67 percent; there are only 11 of them on schedule.

• Increase in weekend games from 549 to 568, much of the boost coming on Saturdays. Previously the NBA avoided Saturdays and Sunday afternoons during football season to dodge conflicts.

Teams that have seen versions of their schedules can petition the league for changes.

The Brooklyn Nets have received several expressions of interest from parties looking to purchase the franchise. 

Mikhail Prokhorov has hoped to fetch around $2 billion for the franchise.

Alibaba Executive Vice Chairman Joe Tsai has expressed an interest in the team, according to a source.

The majority stake sale comes after a failed attempt to sell a minority interest in the team.

The NBA has considered banning pick swaps between drafts in which a team already owes its pick to other teams.

The change in rules has been on the agenda of the competition committee but it has not yet been debated at length.

The Brooklyn Nets included a 2017 pick swap in their trade with the Boston Celtics that essentially saw them trade three consecutive first rounders.

The Stepien Rule prohibits teams from trading away first round picks in consecutive years.

The NBA Board of Governors unanimously approved the Pistons’ relocation from The Palace of Auburn Hills to Little Caesars Arena in downtown Detroit.

The Pistons will begin playing this upcoming season at Little Caesars Arena.
