Golden State Warriors superstar small forward Kevin Durant has reportedly yet to run as he continues to recover from a right calf strain, according to Marc Berman of the New York Post.

How Durant reacts to a running session will be the big hurdle for the Warriors star. Golden State has already ruled Durant out for Game 2 of the NBA Finals, which is on Sunday. The Warriors are down 0-1 in the best of seven series.

Nevertheless, according to an NBA source, the Warriors expect Durant to return to the series and are hopeful it will be no later than Game 4 in Oakland, but have no assurances.

The NBA source said Durant, who suffered a partially torn calf muscle on May 8, has yet to run. How Durant, a free agent who is expected to eye the Knicks, reacts to a running session will be the big hurdle.

In the 2019 playoffs, Durant is averaging 34.2 points, 5.2 rebounds and 4.9 assists. The two-time Finals MVP is shooting 51.3 percent from the field, 41.6 percent from beyond the arc and 90.1 percent from the free-throw line.

Game 3 of the series is on June 5. Durant will have three days after Game 2 to try and get ready for the Warriors. Game 4 is on June 7.
