The controversial ending of the Panthers' win over the Patriots on ESPN's "Monday Night Football" raised questions and eyebrows on Twitter, where football players and athletes from other sports weighed in on the pass interference penalty that wasn't.

Cardinals kicker Jay Feely thought the play, in which Panthers linebacker Luke Kuechly appeared to impede Patriots tight end Rob Gronkowski's progress, was definitely a penalty.

Free agent punter Chris Kluwe was among those who thought a no-call was the right call.

But then again ...

Baseball has taken steps to apply instant replay more often next season -- a big change in a sport where the umpire traditionally gets the last word, even when the call was incorrect. That mindset seemed to be reflected in many of the MLB player tweets we saw.

There also seemed to be support among MLB players for calling the play a penalty.

The ending was a topic of conversation outside the sports world, too:
