Simmons ruled out two days after incredible return

Australian basketball star Ben Simmons has suffered another injury setback just two days after his long-awaited return.

Simmons suited up for the Brooklyn Nets on Tuesday and starred in the 147-114 victory over the Jazz, almost three months since his previous game.

But on Thursday morning Simmons was ruled out of the Nets' game against the Suns due to a new knee issue.

Leading NBA journalist Shams Charania described it as a "left knee contusion" sustained during Tuesday's game.

Before Tuesday's game he had not set foot on an NBA court since November 7.

The 27-year-old sparked the lowly Nets from the bench, dishing six assists in his first four minutes to open up a big first quarter lead over the Utah Jazz.

With Simmons pushing the pace and not missing a shot, Brooklyn never relinquished that advantage as they gave the Jazz a 147-114 lesson on home court.

The former All Star finished with 10 points, 11 assists and eight rebounds in just 18 minutes, flirting with a triple double and perhaps reviving the club's faint playoff pulse.

Simmons was applauded by fans as he left the court, but now they won't be seeing him again for an indefinite period.

Nets coach Jacque Vaughn was full of praised after his comeback.

"Once he said he was ready to go, I had no qualms he was going to be able to push the pace for us and get back to the high energy, high octane pace he's played with with this group.

"You see how he just impacts other people, he makes other dudes better. He likes doing that and when you get a guy who wants to do that on a nightly basis, it's infectious.

"The ball movement tonight, he was the reason for it… you can't ask for anything more, especially with the time he's missed."
