LeBron James believes the NBA video game 2k18 is so realistic that he admitted to using it to prepare for Isaiah Thomas' return.

"I play a lot of NBA 2K," James told Cleveland.com. "It's the most realistic basketball game you could ever play."

"I mix and match a lot of line-up changes and things of that nature to see how we can be really good. I've done that."

While the Cavaliers await Thomas' season debut, expected sometime in December, James said he's used the top selling video game to prepare for the star guards return.

James said so far the experiment has been "pretty good" and it has him excited about the future link-up.

The star guard participated in a four-on-four game on Wednesday along with forward Tristan Thompson and rookies Cedi Osman and Ante Zizic.

Thomas moved with ease and didn't seem too restricted during the recent pick-up game, according to reports.

Cavaliers head coach, Tyronn Lue, was present at the scrummage and said that Thomas absorbed some contact and overall "looked good".

Thomas recently teased fans about his anticipated return but later said he would not jump into it unless he knew he could average 30 points a night.

The 28-year-old remained sidelined with hip injuries he sustained before being shipped from the Celtics in the summer blockbuster trade for Kyrie Irving.
