Is it possible to have my Nexus7 connect to both the TV with HDMI and a wired game controller?

[PompiPompi]

I wish to play with my Nexus7 on my HDMI TV but also use two wired game controllers connected to my tablet.
Since Nexus 7 has only 1 micro USB port, I need to connect all 3 to the same USB port.
So 2 controllers and an HDMI output to the TV on the same micro USB?
Is it even possible? Which adapter do I need to get for this kind of setup?
