The 2022-2023 NBA Season is right here. Tuesday's night will have a two-game schedule. It includes the 2022 NBA Champion, the Golden State Warriors hosting the Los Angeles Lakers, after a Ring Ceremony at the Chase Center. And the Boston Celtics hosting the Philadelphia 76ers. However, not all the key players will be available to play for their franchises in the opening week.

In fact, among the most anticipated returns for this season was Jamal Murray of the Denver Nuggets, and Khris Middleton of the Milwaukee Bucks. However, the Canadian point guard was listed as a day-to-day by the Nuggets, according to Sean Cunningham of ABC 10 Sacramento. While Middleton won't have his return to court at least for the first few weeks, according to Shams Charania of the Athletic.

Other key players such as Lonzo Ball, who had a break out last season with the Chicago Bulls, will be out for the upcoming season due to a knee surgery from which he will be recovering. As well as Spanish point guard Ricky Rubio, who is expected to be back at least on December, according to Marla Ridenour of the Akron Beacon Journal. However, there are players who could come back earlier but at least not for the season opener.
