"Ryan had a hamstring problem so has been working with our medical team since he returned here," Howe told reporters.
The 32-year-old has started all four matches for Bournemouth this season and scored in the 2-0 victory over promoted Cardiff City in their league opener.
Howe said defender Charlie Daniels was another injury concern, having picked up a niggle in the international break but was happy to welcome midfielder Junior Stanislas back from a knee problem.
"Junior is working his way back to fitness. A big positive was that he came back into training during the international break. He won't be ready for this weekend but we're pleased with his progress," Howe added.
