Should Patriots Have Challenged Fourth Down Incompletion?

With the Patriots trailing 27-13 in the fourth quarter, Jacoby Brissett hurled the ball 41 yards to Ja'Lynn Polk. The wide receiver appeared to make the catch between two 49ers defenders for a New England first down.

However, the refs deemed the improbable catch incomplete, ruling that Polk did not get both feet inbounds when he hit the sideline. The rookie wideout didn't agree with the call, according to MassLive's Mark Daniels.

"It was a catch, to me. That's what I think," Polk said, per Daniels. "But shoot, it is what it is. I feel like, in my opinion, I think that's a catch."

The Patriots had a challenge, but Jerod Mayo opted not to throw the flag. Had the ruling on the field been overturned, it would have given New England a first down in San Francisco territory. When you look at the replay, Polk's shoulders appear to fall out of bounds, but not his feet. He told MassLive no one told him the reason for the ruling.

New England dropped its third straight game and second consecutive blowout. Based on the replay, should Mayo have challenged the play? Sound off in the comments below.
