Jefferson nearly registered his third straight game with at least 20 points and 10 rebounds but left the game with six minutes remaining with a mild groin strain and did not return. Michael Kidd-Gilchrist had 13 points and 11 rebounds for the Hornets, who have won back-to-back games for only the third time this season. The Hornets targeted Hayward this offseason as top restricted free agent, signing him to a seven-year, $63 million contract offer sheet. [...] Gerald Henderson and Walker both knocked down 3-pointers to help the Hornets build the lead back to 21 with 3:23 left in the game and the Jazz never challenged again. Stephenson missed his second straight game with a groin injury and coach Steve Clifford said he will be out at least through Christmas.
