The two-time world title challenger was miles ahead of Tetteh in terms of skill level and just cruised through the first four rounds in sparring mode as new promoter Rodney Berman watched on at Emperors Palace.
In the fifth, Tetteh seemed to be hurt and take a knee, although Murray unloaded whilst the Ghanaian was down and the referee failed to call the original knockdown. Another round of taking some crushing body shots from Murray and Tetteh was eventually pulled out as the seventh round started handing the Briton a 27th win and a twelfth stoppage.
The St Helens man now moves on to a higher-profile fight in Monte Carlo this summer, with a world title challenge to follow in November as part of Murray’s big money deal with Berman.
Also on the Kempton Park bill, Paul Kamanga kept his unbeaten record intact as the light-welterweight prospect stopped Adam De Moor in seven rounds following a barnstorming battle between the two fighters.
The 20 year-old improved his record to 11-0 with an eighth career KO as home fighter De Moor eventually wilted under the tremendous pressure applied by the Congolese puncher with just one round to go.
