The Oklahoma City Thunder’s next playoff game will be Sunday at the earliest. The Thunder would play Sunday if the Memphis Grizzlies eliminate the top-seeded San Antonio Spurs on Friday night in Memphis. If that happens, tipoff for Game 1 in the Western Conference semifinal will be at noon inside Oklahoma City Arena, and the game will be nationally televised on ABC. If Game 7 is necessary for the Grizzlies-Spurs series, the Thunder would not play Sunday and its second-round series would begin either Tuesday or Wednesday. OVER-AND-NOT-BACK With 14.8 seconds remaining in the game and the Thunder clinging to 98-97 lead, referee Bill Spooner initially whistled Kevin Durant for an over-and-back violation when he tiptoed on the midcourt line after catching the ball on an inbounds play. Spooner quickly huddled with other game officials and overruled himself. On an inbounds play in the last two minutes, a player is allowed to establish his position in the backcourt. Durant’s momentum carried him into the backcourt, which is where he established position. DOUBLING UP Denver entered Game 5 averaging 39.8 free-throw attempts per game while OKC was averaging 32.5. On Wednesday, the Thunder had exactly twice as many attempts and conversions, finishing 34 for 42 to Denver’s 17 for 21 (both .810). SEA OF BLUE For the third consecutive home game, blue T-shirts were placed on every seat inside the Thunder’s home arena. For Game 5 on Wednesday night, the shirts came compliments of Devon Energy. Game 1 shirts came compliments of Chesapeake Energy. Game 2 shirts were paid for by U.S. Fleet Tracking. CELEB SIGHTINGS Those spotted in the crowd for Game 5 included Gov. Mary Fallin, former Thunder player Desmond Mason, pro golfer Scott Verplank, former OU football standouts Roy Williams and Jammal Brown, plus Thunder season-ticket holder Barry Switzer. “ELLEN” APPEARANCE On Wednesday’s Ellen DeGeneres Show, Rumble the Bison helped Oklahoma native Kristin Chenoweth surprise the host with a variety of Thunder merchandise and collectibles. Two courtside seats were also included and, in collaboration with the show, fans can bid on the tickets to attend an upcoming Thunder playoff game. All proceeds will benefit The Gentle Barn, one of Ellen’s favorite charities. Fans can log on to thunder.nba.com to bid. The date, time and opponent are yet to be determined and will be mutually agreed upon between the winner and the Thunder. The auction will conclude Saturday. BIG-LEAGUE SUPPORT Minnesota Twins pitcher Nick Blackburn, an Ada native, has become a self-proclaimed Thunder “super fan.” Before the Thunder arrived three years ago, “I couldn’t have told you anything (about the NBA),” Blackburn admitted. Blackburn and his wife, Alicia, were introduced to pro basketball when the New Orleans Hornets temporarily relocated here in 2005-06 after Hurricane Katrina and got hooked after attending their first Thunder game. The 29-year-old Blackburn became a season-ticket holder and owns Kevin Durant and Russell Westbrook jerseys. Blackburn’s story is profiled on w.espn.com. CANCEL THAT ORDER The Nuggets will have to cancel — perhaps refund — those fans who ordered tickets for Game 6 at the multiple bequests of the public address announcer inside the Pepsi Center who implored them to do so during and after Game 4 on Monday night. TIEBREAKER With the Thunder victory, the No. 4 vs. No. 5 playoff series now stands at 28-27 entering this season since the NBA began its current playoff system in 1984.
