Matusz (back) will miss the next one-to-two weeks, Roch Kubatko of MASN reports.
EDGE Analysis
Matusz underwent an MRI on Friday after feeling discomfort in his back earlier in the week. The MRI revealed three bruised ribs and a lower back strain, so the Orioles will put Matusz on the shelf for at least a week before letting him take the mound again.
