The Buffalo Bills continue to extend their lead over the Indianapolis Colts, but the Colts refuse to go down without a fight. Following a touchdown strike from Josh Allen to Stefon Diggs, Philip Rivers found Jack Doyle for a late-game score to narrow their deficit.

Throughout the game, Rivers' team had success throwing to their tight ends. And with the Indianapolis needing a quick score, Rivers led a clutch drive to give Indianapolis a chance to make it a three-point game.

As for Doyle, he was wide open on the play and likely won't have many touchdowns as easy as the one he had in the fourth quarter. The veteran tight end would also catch the two-point conversion to give the Colts an opportunity to upset the Bills late in the game.

During the regular season, the Colts used all three of their tight ends in the passing game in different situations. Altogether, Doyle, Mo Alie-Cox, and Trey Burton have seen playing time in Frank Reich's offense.

Of course, we know Rivers — who could be playing in his final game if the Colts lose — loves to target his tight ends. When Rivers was with the Los Angeles Chargers, he loved to find Antonio Gates or Hunter Henry in the aerial attack.

With a loss sending Indianapolis home, it's apparent that the Colts may have found a weakness in Buffalo's defense. If Indy are going to overcome their deficit to win, Rivers may continue to look for Doyle through the air.
