There is “cautious optimism” within the Golden State that Warriors star Stephen Curry could return before the end of March, ESPN’s Shams Charania reported Wednesday on NBA Today.

Curry, sidelined since January 30, has missed 18 games with patellofemoral pain syndrome, or runner’s knee.

Still, both he and head coach Steve Kerr have remained hopeful about a return before the regular season ends, and Charania’s update suggests it could happen in the coming weeks.

“I’m told he had a strong on-court workout Tuesday afternoon in Boston,” Charania said while speaking with ESPN’s Malika Andrews.

“Starting to run, cut, move, take some slight contact, like the Stephen Curry that we know. The most important part though is that he’s not experiencing the swelling that he’s had over the last several weeks or a month ago, when he needed to get a PRP injection, from my understanding, due to those knee issues.”

Curry is still limited to individual workouts and hasn’t resumed team activities, but his increased on-court work is an encouraging sign.

According to Charania, the next step will be building conditioning and ensuring comfort with running and jumping on his right knee.

Despite playing just 39 games, Curry has remained elite, averaging 27.2 points, 4.8 assists, and 3.5 rebounds, earning his 12th All-Star nod.

The Warriors are 23-16 with him and just 10-19 without him.

At 33-35, Golden State still holds a play-in spot, leading the 11th-place Grizzlies by 9.5 games, though they trail the Clippers and sit just half a game ahead of the Trail Blazers.
