Bill Belichick will certainly have plenty of teaching moments to show his team following Sunday’s 23-21 win over the Bills, but the Patriots coach chose to focus on the positives in his postgame press conference.

ORCHARD PARK — The Patriots escaped Buffalo with a 23-21 win over the Bills, thanks to a 35-yard field goal from Stephen Gostkowski with five seconds left. Quarterback Tom Brady ended up going 29-for-52 for 288 yards with two touchdowns and one interception. In his first game with the Patriots, wide receiver Danny Amendola had 10 catches for 104 yards, while Shane Vereen added 14 carries for 101 yards and 7 catches for 58 yards.

Here are a few quick notes on the game:


ORCHARD PARK, N.Y. — With just over two minutes left in the first half Sunday, Danny Amendola limped off the field holding his groin.

Amendola was running a crossing route in the end zone as Tom Brady scrambled on a short run inside the Bills 10. The injury-plagued receiver immediately grabbed for his groin. Amendola was listed as limited in practice on Wednesday and Thursday with a groin injury before being cleared for full practice on Friday and listed as probable for Sunday’s season-opening game.

ORCHARD PARK, N.Y. — Apparently the sunny weather got to Patriots starting linebacker Brandon Spikes.

Just one series into the game, played under clear skies and temperatures in the mid-60s, Spikes came out due to dehydration. He was listed as questionable to return.

With Spikes out of action and on the sidelines getting treatment, the Patriots went primarily with their nickel (five DB package). It was successful as the Bills were just 1-for-3 on third down and were held scoreless.

Newly retired Ravens middle linebacker Ray Lewis made quite the debut for ESPN on Sunday. During his first appearance on ESPN’s pregame show, Lewis weighed in on Aaron Hernandez and what he believes the Patriots should have known about their former tight end now accused of first-degree murder.

ORCHARD PARK, N.Y. — Leon Washington is the final inactive for the Patriots in their season opener against the Bills at Ralph Wilson Stadium. The move is a bit of a surprise as he was brought back to the team on Saturday and the veteran returner was on the field two hours before kickoff working out with strength and conditioning coach Harold Nash.

ORCHARD PARK, N.Y. — Partly cloudy skies and temperatures in the mid-60s are expected for the 1 p.m. ET kickoff between the Patriots and Bills here at Ralph Wilson Stadium in Western New York. It’s expected to be a breezy but mild afternoon, with wind out of the northeast at 11 MPH.

Rob Gronkowski (back/forearm) was listed as doubtful on Friday’s initial injury report, and on Saturday he was officially ruled out for Sunday’s season opener against the Bills.

The Patriots made four roster moves Saturday, most notably re-signing running back and return specialist Leon Washington. They had originally signed Washington as a free agent in March, but they released him last Sunday.

The Patriots also added offensive lineman Josh Kline to the 53-man roster. Kline had been signed to the practice squad on Wednesday.

FOXBORO — Rob Gronkowski was officially limited for the third straight day of practice on Friday and is listed as doubtful to play on Sunday in the season opener against the Bills at Ralph Wilson Stadium.

It is not known whether Gronkowski will even make the trip with the team when they leave for Western New York after a team walkthrough on Saturday.

In a sign that he is completely fine and ready to go, receiver Danny Amendola (groin) fully participated Friday for the first time this week and is listed as probable.
