FTP $26K Guaranteed; AK on TT4 vs bet into raiser... wtf?

[blankoblanco]

Pretty early, no big reads. My pre-flop image should be pretty snug... raised in EP one time before, once in LP, none showed down. What the hell do I make of this? I assume a T either c/c or c/r's. Is a low pair likely to lead out here? A 4? Does he have nothing and just assumes I missed this flop?
