Narrative:

At cruise FL330; EICAS displayed message - right rev unlocked. The aircraft sound changed to a rumble and we were unable to maintain altitude. Captain was pilot flying and first officer was pilot monitoring. We ran the qrc/ immediate action items for right rev unlocked and advised ATC requesting a lower altitude. Another EICAS message was received for right engine oil press. Itt displayed (red) over temp and the right engine oil pressure gauge indicated 3 (red). We ran the QRH procedures for right engine oil press and in-flight engine shutdown procedures as directed. ATC was advised that we would be landing single engine with over 30 souls onboard and 6700 lb of fuel. We also requested emergency service vehicles. Captain advised dispatch; flight attendant; and passengers about the situation. Single engine procedures from the QRH and normal checklists were completed for descent and landing. Captain flew the single engine approach and landing without incident. Emergency vehicles met and examined aircraft exterior prior to taxi in to the gate.
