WATCH: Forget Aaron Rodgers -- Vikings struggle to contain a squirrel

An invader at TCF Bank Stadium caused the Minnesota Vikings a great deal of trouble Sunday.

No, we're not talking about quarterback Aaron Rodgers or any of the other Green Bay Packers on the field for their Week 11 matchup with the Vikings. This intruder was much smaller, furry and extremely good at evading tacklers.

A squirrel got loose on the field before a Packers kickoff in the first half.

Watching Vikings stadium officials struggle to contain the wayward critter was a humorous moment in an otherwise serious showdown. The two NFC North rivals entered this matchup knowing first place in the division was at stake.
