Golden State Warriors coach Steve Kerr has confirmed Kevin Durant is a major doubt for the second match of the team’s playoff series with Portland Trail Blazers.

The Warriors are the top seeds in the Western Conference and they secured 121-109 victory over the Trail Blazers in the first match of their best of seven series at the Oracle Arena on Sunday.

Small forward Durant was Golden State’s top points scorer during that match, but he sustained a calf problem on his way to that 32 point haul and he is now a major doubt for Wednesday’s second match.

Kerr admits they will take no risks with the 28-year-old, who missed 19 games of the regular season due to a knee injury.

“If he didn’t practice, there’s concern,” Kerr told local media. “He’s questionable. You have to be careful.”

Durant is not the only injury concern for the Warriors heading into Wednesday’s contest, as point guard Shaun Livingston is struggling with a finger injury, while small forward Matt Barnes is continuing his recovery from an ankle problem.

Golden State have won the Western Conference title in each of the last two years, defeating Houston Rockets in 2015 and Oklahoma City Thunder 12 months ago.

Kerr’s men will be looking to make it a hat-trick of titles this year and they are priced at 1.03 to open a 2-0 advantage in their series with the Trail Blazers, who are available at 12.00 to level the contest up at 1-1.
