Memphis Grizzlies guard Luke Kennard will miss a minimum of two weeks recovering from a bone bruise in his left knee and forward Xavier Tillman Sr. now is considered week to week recovering from his own injured left knee. The Grizzlies provided the update Monday. Kennard played only six minutes Nov. 14 in a loss in Los Angeles to the Lakers and had missed the past two games. Memphis said Kennard, acquired at the trade deadline last season, will be reevaluated in two weeks. Tillman has been Memphis’ fifth-leading scorer averaging 9.3 points and second with 6.7 rebounds a game. He also was hurt in that same loss to the Lakers, playing 22 minutes before leaving the game.
