Nuggets coach Michael Malone attributed Jamal Murray’s left calf strain to a specific moment during Game 4 between the Nuggets and Lakers, but he also indicated Monday that Murray might have already been dealing with an injury. “I think it was one movement that kind of worsened the calf,” Malone said before Game 5 of the first-round series at Ball Arena. With about eight minutes remaining in the fourth quarter Saturday night in Los Angeles, Murray appeared to reach for his calf after attempting a jump shot.
