Not even Tim Tebow can help the Denver Broncos out of this jam.

Just as the Broncos survived a wild first round of the NFL playoffs by beating the Pittsburgh Steelers on Sunday, their trouble was just starting off the field.

A spokesperson for Texas A&M University said the school might take legal action against the Broncos for using the school’s trademarked “12th man” phrase before Sunday’s game, according to KBTX TV in College Station, Texas.

Jason Cook, the vice president of marketing and communications at Texas A&M, on Sunday said on Twitter:

“FYI Broncos, the 12th Man belongs to Texas A&M. We saw the flag today and will defend our trademark.”

The Broncos, during pregame festivities at Sports Authority Field, had a man parachute into the stadium holding a “12th man” flag.

The Seattle Seahawks did something similar for their playoff game last season against the New Orleans Saints. In that case, Texas A&M threatened legal action and the two sides settled out of court, after the NFL team was forced to pay the school a fee. They now have a contract that allows the Seahawks to use the phrase.

Broncos rookie Von Miller, already a Pro Bowl selection, is a former star linebacker at Texas A&M.

The Broncos-Steelers game Sunday was the most watched NFL game of the year in Denver, by far, according to CBS.
