Corrections officials say an inmate at an eastern Colorado prison assaulted and injured a guard.
  
The Colorado Department of Corrections said in a statement on Friday that inmate Ryan Spear "seriously assaulted" a correctional officer at the Limon Correctional Facility.
  
The department says other prison staffers were able to restrain Spear. The statement says the officer was treated at a hospital but the injuries were not life-threatening.
  
The guard was not identified.
  
Spear, who is 29 and has been in prison since 2010, was transferred to another facility.
