"Chavvy's just in 'calm-everything-down' mode," manager Kirk Gibson said before Sunday's series finale vs. the Giants.
Gibson said Chavez has been taking it easy to try to reduce inflammation in the knee, which Chavez said has been helping.
"When you do nothing, you feel much better," Chavez said. "It's getting there."
Chavez was a key contributor off the bench before he went on the disabled list. The veteran third baseman had a .795 OPS (on-base plus slugging percentage) and three home runs while serving primarily as a reserve third baseman.
The starting third baseman, Martin Prado, has played all but one game. Since Chavez went on the DL, Prado is hitting .217 (10-for-46). The D-backs played Didi Gregorius, who is usually a shortstop, at third base for one game.
Chavez said doctors hadn't set a timetable for when he could return, but sitting out isn't something he enjoys.
"It's very frustrating," he said.
