--Defensive tackle Kris Jenkins' knee seemed to hold up fine Saturday night in his first game back from major knee surgery.
Jenkins has missed 30 of 35 games over the past two seasons, including 15 last year after tearing his ACL in the regular-season opener.
He played about one quarter against the Buffalo Bills and recorded one tackle.
"I am glad to be back out there," Jenkins said. "I have had two years off. I was nervous going back out there because it has been awhile, but I know one speed and it picks up quick.
"It is just one of those things I have to get backed used to doing. The more games that we go through, the better I will get at it. Hopefully by the end of the preseason I will be back to my true self."
Last week, Panthers defensive line coach Sal Sunseri said Jenkins is improving, but admitted the former two-time All-Pro isn't all the way the back.
"I don't think he's there yet," Sunseri said. "I believe that Kris has confidence in his knee, and he wants to be at a certain level and all that, but he's not there yet. And he's not there yet. But he's working hard."
--Safety Mike Minter, the team leader on defense, did not play Saturday night because he was in Oklahoma to be with family following the unexpected death of his mother, Florida. Funeral services were scheduled for Monday, Aug. 14.
Coach John Fox has told Minter to take as much time as he needs.
"We're on his schedule right now," Fox said.
--Although Jake Delhomme looked sharp in the preseason opener, the same can't be said of backup Chris Weinke.
Weinke completed 7 of the 10 passes he attempted, but only for 38 yards. He was sacked once. He led five drives, but the Panthers failed to pick up any points.
--Fox was 0-for-2 in instant replay challenges Saturday night.
The first challenge came when fullback Casey Cramer fumbled in the third quarter. Fox challenged the ruling on the field, but the call was upheld.
On the ensuing drive, Fox challenged running back Lionel Gates hadn't scored on a 2-yard run, but officials upheld the ruling on the field.
QUOTE: "I think the defense came out and played well. They played together. Everyone was just in sync with each other. I think we played aggressive and we played hard. It was a Carolina defense. I think the offense was awesome and played great. With Steve (Smith) being on the sideline, that was a tremendous passing attack. DeShaun (Foster) getting in there and running, it just looks very promising for this year." -- Panthers DT Kris Jenkins on Carolina's 14-13 win over Buffalo. The Panthers' first team outscored the Bills 14-0 in the first quarter.
--WR Efrem Hill had a rough preseason debut against Buffalo, looking shaky on punt returns.
--LB Adam Seward played a nice game for the Panthers on Saturday night, recording a team-high six tackles and two on special teams. He also blocked a punt on special teams.
--DT Tony Brown, the Defensive MVP of NFL Europe, had two sacks for the Panthers against Buffalo.
--WR Keyshawn Johnson looked good in his Carolina debut with two catches for 27 yards on the opening series.
--RB Eric Shelton was the fifth running back off the Carolina bench, but did well, rushing for 18 yards on four carries.
--K MacKenzie Hoambrecker could get cut this week now that John Kasay appears to be at full strength.
--The Panthers got a nice effort out of undrafted rookie cornerback Jarrett Bush, who knocked down two passes in the first half.
BATTLE OF THE WEEK: WR Keary Colbert against Drew Carter for No. 3 WR spot. Colbert drew the start Saturday night in the absence of Steve Smith, a pretty good indication the team views him as the third receiver. And Colbert looked sharp, catching two passes for 23 yards on the team's first drive. However, it's going to be tough to keep Carter off the field because he keeps making big plays. On his first play of the game Saturday night, Carter caught a 14-yard strike from Jake Delhomme for a touchdown. The Panthers appear to have four very formidable receivers in Smith, Keyshawn Johnson, Carter and Colbert, which is a very nice problem to have if you're coach John Fox.
OTHER BATTLE FRONTS: Damione Lewis against Jordan Carstens against Kindal Moorehead at backup DT. It's unclear at this point if the Panthers will keep four or five defensive tackles, but they may be forced into keep all five because they have such good players there. Carstens has been a constant there for the past two years and will stick around. Lewis will also make the team given his big two-year, $3.9 contract. Moorehead is a question mark and is currently working as the fifth defensive tackle, but still stands a good chance to make the roster given his athletic ability and experience. If that happens, the Panthers will likely only keep four defensive ends, which will probably be Julius Peppers, Mike Rucker, Al Wallace and Jovan Haye.
PLAYER OF THE WEEK: QB Jake Delhomme played just one series against the Buffalo Bills and went 5-for-6 for 64 yards with a touchdown. Delhomme has been resting his shoulder in camp because of fatigue, but looked extremely sharp in the game.
ROOKIE REPORT: RB DeAngelo Williams was held to 1 yard on seven carries before breaking lose on a 20-yard scamper on his final run.
--CB Richard Marshall struggled some in coverage for the Panthers and still has a ways to go.
--T Rashad Butler is still lighter than the Panthers want him and probably won't see any action this year.
--LB James Anderson had a sack in his NFL preseason debut.
--S Nate Salley saw a lot of action in place of Mike Minter.
--The Panthers are very high on C Will Montgomery, who could prove to be a steal in the seventh round.
INJURY REPORT: The Panthers didn't appear to suffer any major injuries on Saturday night. The team is hoping to get Steve Smith back on the field this week after missing the last two weeks of camp with a strained hamstring. Tight end Kris Mangum is expected to miss at least another week or two with a plantar fascia problem.
