QPR missed the chance to move up to second place in the Championship as they played out a goalless draw with Norwich at Carrow Road.
Teemu Pukki went closest for the hosts before the break when his low shot across QPR goalkeeper Seny Dieng cannoned back off the left upright.
Hoops top scorer Chris Willock thundered a shot from range against the foot of the same post moments after coming on before Angus Gunn saved at full stretch to keep out Lyndon Dykes' point-blank header.
Dieng then came out to block Onel Hernandez's close-range effort before Grant Hanley struck the post with the last kick of the game.
