Colorado Rockies starting pitcher Jhoulys Chacin will be sidelined at least another week with a sore throwing shoulder.

The Rockies learned the results of Chacin's MRI on Tuesday morning. The team announced he has right shoulder inflammation, but no structural damage.

Chacin was Colorado's top right-handed starter in 2013, going 14-10 with a 3.47 ERA. But he was limited since the start of spring training and had yet to throw off the mound before he was shut down on Sunday.

Chacin said Tuesday that his shoulder was feeling better, but the injury could prevent him from being ready for the start of the regular season.
