Conley, who has been sidelined with a hamstring injury, was cleared to play less than an hour before tipoff.
Donovan Mitchell was also cleared to play despite a lingering ankle injury.
The hamstring issue caused Conley to miss Utah's first five games in the Western Conference semifinals against the Clippers. He originally suffered the injury late in the regular season and reaggravated it in Game 5 of the first-round series against the Memphis Grizzlies.
Mitchell said after the Jazz's Game 5 loss to the Clippers that his ankle is still causing problems after originally spraining it on April 16.
The Jazz have lost three straight games to the Clippers after winning the first two games of the series. Their defense is allowing 123 points per game since Game 3, and they will look to stave off elimination at the Staples Center on Friday night.
Conley led the Jazz with six assists per game during the regular season. He also averaged 16.2 points per game on 41.2 percent three-point shooting.
Now that Conley is back, he will be the primary ballhandler for head coach Quin Snyder and provide Mitchell with his usual partner in crime in the backcourt.
