Leonard underwent surgery to repair a partial tear in his right ACL on July 13 and is expected to be out for an extended period of time.
"Oh, we don't even breach that," Frank, the Clippers' president of basketball operations, said when asked if he anticipates Leonard playing this season. "I think at this point, it's just no one knows when you're dealing with a recovery from an ACL [injury], the time frame.
"Even just to save you guys [from asking] throughout the year, is no one knows. You just attack it day by day. He has a very detailed plan with a great group, and we'll just let his body and the doctors tell us when it's the right time."
Leonard injured his knee during the fourth quarter of Game 4 of the Western Conference semifinals against the Utah Jazz on June 14. He missed the Clippers' final eight playoff games with what the team called a sprained right knee.
Center Serge Ibaka, who is recovering from back surgery in June during the playoffs, will be limited and participate in noncontact drills to start training camp, Frank said.
Rookie point guard Jason Preston, the 33rd overall pick in the 2021 draft, injured his foot in a group workout this week and will not be available to start training camp next week in San Diego. Frank said the severity of the rookie's injury will be determined in the next couple of days.
Frank also would not discuss whether Clippers players and staff members were fully vaccinated as camp is set to begin Tuesday.
"Personally, I'm a huge advocate of the vaccinations. I believe in the science and believe in the evidence as a personal viewpoint," Frank said. "But in regard to speaking on behalf of players or staff, I'm not comfortable sharing that type of information other than personally, what my beliefs are and what we spread and what we educate everyone in the organization. But ultimately, that's not my news to share."
