NEW YORK -- With Steve Kerr back on the Golden State bench, the NBA is trying to determine who will coach the Western Conference All-Stars.

Kerr returned from back surgery Friday for the Warriors' 122-110 win but is ineligible to coach in this season's All-Star Game because he did so last year. The league is deciding if Warriors assistant Luke Walton would be eligible.

Spokesman Tim Frank says: "We are reviewing our rules around the West coach situation to determine what is appropriate."

The coaches for the All-Star Game are determined by the teams with the best winning percentage in each conference through Jan. 31. Tyronn Lue, who replaced the fired David Blatt in Cleveland on Friday, would guide the East if the Cavs remain on top.

In Kerr's absence, Walton led the Warriors to a 39-4 record and a two-game lead over Gregg Popovich's San Antonio Spurs in the West.

As for talk of Walton's potential eligibility, Kerr said, "I heard they might send him, which I find amusing because they didn't give him any wins, and yet they're saying you're the coach of -- you're the new coach.

"So, I don't know what they're going to do with that, but I know that if they do it by the normal rule, then Gregg Popovich will be going to Toronto, and I know how excited Pop is to coach another All-Star Game," he joked.

Coaches are not allowed to coach All-Star Games in consecutive years, a rule that dates to Pat Riley's dominance of the West when he coached the Lakers in the 1980s. Had Kerr been coaching all season, Popovich would have already secured the West spot.
