Johnny Walker admits Octagon rust slowed him early but he recovered to score a brutal second-round TKO over Zhang Mingyang at UFC Shanghai.

Walker (22-9, 1 NC), the explosive Brazilian striker, survived a particularly hairy opening round before attacking the calves of Zhang (19-7) with a series of hard kicks that dropped him in Round 2. A flurry of punches from Walker followed until referee Marc Goddard stopped the bout at 2:37 inside Shanghai Indoor Stadium.
