With Jamierra Faulkner’s timetable unknown, who’ll back up Courtney Vandersloot?

Guard Jamierra Faulkner’s timetable to return from a second torn anterior cruciate ligament was still unclear as the Sky opened training camp Sunday.

Faulkner missed the entire 2017 season with a torn ACL in her left knee. She came back strong for the first part of 2018 before she was sidelined in July with a torn ACL in her right knee.

Faulkner wasn’t at the Sachs Recreation Center in Deerfield for the start of camp because she had to see a doctor overseas.

With Faulkner seemingly out of the picture for the time being, one of the biggest questions this preseason is who’ll be point guard Courtney Vandersloot’s backup.

Guard Linnae Harper got some of Faulkner’s minutes after she went down last season. In 24 games, Harper averaged two points on 40.4 percent shooting.

New coach James Wade is high on Harper and her work ethic.

‘‘People kind of discredit Linnae Harper and how hard she’s worked — being an undrafted player and working to get on a roster, then to be on that roster and get quality minutes,’’ Wade said. ‘‘I don’t want to count her out.’’

Wade also could turn to Hind Ben Abdelkader, who was signed to a training-camp contract, or second-round pick Chloe Jackson.

‘‘I’m fond of all of them,’’ Wade said.

Copper update

Guard Kahleah Copper is nursing an injury to her right hand after an opponent bent her fingers back during a game in Turkey.

Copper said she’s in some pain, but she doesn’t expect the injury to stand in her way.

‘‘I’m OK,’’ Copper said. ‘‘I was hopping in drills and doing conditioning and still getting ready.’’
