Ben Simmons will not feature for the rest of the regular season or the upcoming Play-In tournament, according to Brooklyn Nets head coach Steve Nash.

Simmons is yet to debut for the Nets following his February trade from the Philadelphia 76ers, following his bitter and prolonged stand-off with the team that drafted him. The Australian guard has subsequently not played all season.

The former All-Star had an epidural last month to alleviate pressure in his back as he struggles to build his conditioning up to a level fit enough to see him return to action.

Simmons has started participating in limited practice, but Nash confirmed on Monday that the 25-year-old will not return before the end of the regular season, or for the Play-In, which takes place between April 12-15.

The Nets are on course to require two wins in the Play-In tournament to qualify for the playoffs, sitting in 10th place in the Eastern Conference after three defeats in their last four games, with an overall regular-season record of 40-38.
