Hundley was batting .301 with a career-high 21 doubles, 10 home runs and 43 RBIs. He left Sunday's game against the San Francisco Giants with a stiff neck.
Rockies manager Walt Weiss said Hundley was ''still sore a few days later,'' which raised concerns. Weiss hopes to ''get him into the offseason healthy and have a normal offseason,'' and didn't want to risk Hundley's readiness for 2016 by pushing him this month.
Murphy was a third-round pick in the 2012 draft and began the season at Double-A New Britain. He then hit .271 with seven home runs and 19 RBIs in 33 games with Albuquerque.
This is Murphy's first appearance on a Major League roster.
