Murphy (forearm) will undergo testing Monday to assess how his fracture is healing, MLB.com's Thomas Harding reports.
Murphy suffered a fractured forearm in mid March, with his recovery timetable estimated at four-to-six weeks. Rockies manager Bud Black said the catcher has ramped up his exercise program, but a return still shouldn't be expected any sooner than mid-to-late April. Tony Wolters started behind the plate in each of the team's first three games, going 2-for-10 with a pair of singles and a walk. Murphy figures to get most of the playing time against southpaws once he's available, but Wolters likely will make most of the starts versus right-handers.
