The Northern Ireland international started pre-season brightly for the Reds, but a stress fracture in his back led to time in the treatment room and four months on the sidelines.
Against LASK, the 20-year-old came off the bench for an eight-minute cameo, his first taste of competitive action since representing his country in mid-June.
Jurgen Klopp praised Bradley as a real prospect and someone the Reds can count on, and, as one would expect, the young full-back was buzzing to be back after a frustrating injury.
I was hoping we would score more so I could get on the pitch but, yeah, buzzing to be back, Bradley told LFCTV. Its been a frustratingly long couple of months out injured so buzzing to be back.
