NFL's Andy Moeller -- Line Coach Sacked In Cleveland ... After Alleged Fiancee Attack

Seems like it was just a matter of time, but the Cleveland Browns have officially cut ties with offensive line coach Andy Moeller ... after an altercation with his fiancee earlier this month.

As we previously reported, Moeller's fiancee called police and claimed he strangled and beat her at his Maryland home on September 5th.

Cops investigated and determined an "incident of a volatile nature" took place ... but DID NOT charge him with a crime because they couldn't prove beyond a reasonable doubt that Moeller actually attacked his fiancee.
