LAS VEGAS – As the Warriors put their Summer League roster through its paces on Thursday, it was apparent that one particular person was favoring his right knee.
And it wasn't Festus Ezeli.
It was Warriors coach Steve Kerr wearing a sleeve around his knee.
Kerr, who suffers from knee arthritis no doubt tracing back to 20 years of basketball at the college and NBA levels, earlier this week took a Senvisc (fluid) injection to alleviate the symptoms. The helper didn't help.
''They told me about three percent of patients who get the injection have an adverse reaction,'' Kerr said. ''I'm one of them.''
Kerr said his knee swelled noticeably and the result is the brace. The swelling has diminished, he said, but the knee remains tender.
If Harrison Barnes wanted to impress the new coaching staff, mission accomplished – by being available and also by being fully engaged in the process.
"Harrison's been great,'' Kerr said. "He's playing with a lot of pride and focus and intensity. You don't always see that. Some young guys come to Summer League and think, 'I'm too big for this.' Or, 'I shouldn't even be here.' Harrison asked to be here and is working his tail off, so it's been fun to watch.''
Barnes participated in scrimmages and practice drills during a three-hour practice. He won't be playing Summer League ball, though. He plans to return to the Bay Area on Friday, and then visit his home state of Iowa next week.
Andre Iguodala and Draymond Green also made appearances Thursday, both suiting up and working on their own. Kerr took note of their presence, but implied there may be more at work than sheer devotion to basketball.
"It's great,'' Kerr said before breaking into a grin. "Maybe Las Vegas has something to do with it. If Summer League were in Boise, I'm not sure we'd see those guys – nothing against you in Boise.
"But these guys are team players. They want to be around it. They're just gamers. They're ballers.''

Point guard Nemanja Nedovic, who was injured for much of his rookie season, rolled his left ankle on Thursday but Kerr said it doesn't appear to be serious. The only other point guards on the Summer League roster are Walt Lemon Jr. and Aaron Craft, who arrived Thursday from the Orlando Summer League. And Craft is coping with a sore knee.
Forward Lance Goulbourne, who spent last season with the D-League Santa Cruz Warriors, sustained a fractured left wrist and has been relegated to spectator status.
Power forward D. J. White, an Indiana University product who has started 11 NBA games over three seasons, was a late addition. He suited up and worked out but did not participate in team drills.
