Narrative:

Arrived ZZZ operations uneventful flight planning. Both captain and myself note left engine reverser deferred inoperative with history of status messages associated with left engine reverser. Uneventful pushback; engine start; taxi and takeoff. During climb passing 10000 ft MSL; single audible boom accompanied with aircraft yaw to the left. I look down at upper EICAS screen and announce 'engine failure left engine.' captain is hand-flying the aircraft; lowers the nose and controls the yaw. Captain calls for me to do the qrc and he then takes the communication with ATC and informs departure that we have had an engine failure and are returning to ZZZ. The captain and I discuss the engine indications EPR 0; N1 0; N2 0; normal oil quantity; no oil pressure. With these indications and our perceived physical indications we agreed that the engine appeared to have seized. I ran the qrc for left engine severe damage/separation and associated reference action from the flight manual. The captain informs me to send our dispatcher an ACARS message of our situation and our intentions to return to ZZZ which I did and they acknowledged. Captain informed the purser of our situation and our intention to return and notified them that we expected a normal landing. We set up and the captain briefed a single engine approach backed up by the ILS ZZZ. I checked the landing distance for our abnormal confign and expected landing weight and the distance required was approximately 4000 ft with 11000 ft available. We discuss our overweight situation and the captain's intention to land with minimal sink rate and autobrake #2. Captain made a nice approach and landing. Touchdown was smooth and he let the aircraft roll out using right reverser and autobrakes. Captain exited the runway at taxiway C approximately 10000 ft down the runway. Crash crew was waiting and checked the aircraft and brakes. They reported the brake temperature was approximately 200 degrees and that the left engine appeared normal. We returned the aircraft to the gate and accomplished normal shutdown procedures. Captain did a fine job communicating his intentions and flying the aircraft.
