Stefon Diggs was once Josh Allen's top target in Buffalo. Now, he's facing Allen and the Bills twice a year with the Patriots.

On offense, the Bills had some uncharacteristic hiccups, especially in the second quarter. Defensively, the Bills allowed the Saints to rush for nearly 200 yards and average 5.6 yards per carry.

On Sunday night, the New England Patriots went into Highmark Stadium in Orchard Park, NY and handed the Buffalo Bills their first loss of the season, beating their AFC East rivals 23-20.

In his return to Buffalo, a motivated Stefon Diggs delivered the most prolific performance from a Patriots wideout in years. The former Buffalo Bill caught 10 passes for 146 yards, moving the chains eight times in a shocking 23-20 upset victory for New England.

The Buffalo Bills are one of only two teams in the NFL still with an unblemished record in 2025. After defeating the New Orleans Saints (0-4) in Week 4 in a 31-19 final, the Bills and Philadelphia Eagles are the only two sides still sitting at 4-0.

NFL Week 5 continues with the Buffalo Bills hosting the New England Patriots on Sunday Night Football tonight. Start time, schedule and how to watch.

Diggs comes to Buffalo after having his best game of the season. Last week, he caught six of seven passes for 101 yards. He looked like a No. 1 receiver. That ability played a big part in the Patriots success against Carolina. It would go a long way if he did the same thing against his former team.
