Did Gibbs 12-Man Challenge Make Up 4 The Timeout In Buffalo?

I didn't think you could challenge something like that? Are you allowed to challenge a penalty as well? My assumption at the time was if the ref's missed it to bad. It helped make up for that ridiculous challenge earlier in the game when they took a TD away from Sellars, I am still waiting to see a conclusive replay that actually shows him not in, and to actually over turn the call on the field from anything I saw was a joke.
