Peixoto is among four nominees for the Championship’s manager of the month for August after he picked up seven points from three unbeaten games.
He is up against Charlton’s Nathan Jones, Swansea’s Vitor Matos and QPR’s Julien Stephan.
Wolves could have a double success as Lopez has been nominated for August’s player of the month gong.
He contributed two goals and two assists in the three league games last month and has continued that form into September.
Lopez is up against Charlton defender Lloyd Jones, Middlesbrough striker Will Lankshear and Southampton forward Cyle Larin.
