The Golden State Warriors remain reluctant to put a timeframe on Klay Thompson's return from injury, but head coach Steve Kerr said the shooting guard is showing positive signs.

Thompson, who has not played in the NBA since June 2019, participated in team practice on Tuesday for the first time since tearing his Achilles in November last year.

The three-time champion tore his anterior cruciate ligament (ACL) against the Toronto Raptors in Game 6 of the 2019 NBA Finals, before sustaining an Achilles injury during his comeback.

Last week, Golden State put out an injury update, vaguely stating he was making "good progress", but his return to training is a significant step in the right direction.

The five-time NBA All-Star remains months away from a competitive return, however, Kerr was upbeat about his recovery on Tuesday.

"Everyone's excited that Klay is out on the floor," Kerr told reporters. "He basically did every single thing in practice today.

"We didn't scrimmage, we didn't have any live contact, but Klay is just so happy to be playing and we're all so happy to see him part of it. So just a really good first day, first couple of days, and good energy as we start to get rolling."

He added: "Klay looked great. Shooting the lights out. His team won the daily shooting competition. And he was smiling, laughing, joking around, it was really fun to see the old Klay back."

Thompson said on Monday that he was around "75 or 80 percentile of what I need to do" in terms of his Achilles injury rehabilitation, while Warriors general manager Bob Myers indicated December or January may be a likely return timeframe.

Kerr added the Warriors playing group were boosted by Thompson's return to training as the franchise seek a return to the playoffs after missing out the past two seasons.

"Part of it is his spirit, his energy, his joy," Kerr said. "A big part of it too is, 'Yeah, we got Klay.' The confidence level as a group -- we're getting Klay back.

"It makes us all feel better. And that's the sense that I have from our guys."

Kent Bazemore and Kelly Oubre Jr. have left the Warriors this off-season, with veteran Andre Iguodala re-joining along with Serbian power forward Nemanja Bjelica as free agents.

Golden State – who are reportedly among the teams interested in disgruntled Philadelphia 76ers All-Star Ben Simmons – added teenagers Jonathan Kuminga (pick 7) and Moses Moody (pick 14) in the NBA Draft.
