Miami announced Johnson's release Sunday night.
* Andrew Luck knows life in the NFL can't be this easy for a rookie.
The No. 1 overall draft pick threw his first NFL pass for a long touchdown, just like Peyton Manning in 1998, then led Indianapolis to two more touchdowns. Luck one-upped his predecessor by winning Sunday's preseason opener 38-3 over St. Louis - Indy's first preseason-opening win since 1994.
"To get a win, get in the game and put some drives together is great," said Luck, whose first pass was a short dump-off that Donald Brown took 63 yards to the end zone. "But I realize, and the guys in the locker room realize, it's a preseason game and things will be different as the season goes along."
Luck might have the toughest job in football this season - replacing Manning, the longtime face of Indy's franchise. But he showed everyone Sunday that he can do whatever is asked.
The rookie quarterback wound up 10-for-16 for 188 yards with two TD passes and a passer rating of 142.6. Three of the incompletions were drops, two were throwaways, and only one pass, the deep out that rookie T.Y. Hilton barely caught on the sideline, came close to being picked off. It was the most lopsided preseason win for the Colts since a 35-0 rout of Washington in 1966.
Longtime Colts fans had seen it before. Back in '98, Manning's first pass was an 8-yard route to Marvin Harrison, who took the ball and sprinted to the end zone for a 48-yard score.
* Veteran receiver Plaxico Burress is in New England for a workout with the Patriots. A person with knowledge of the tryout tells the Associated Press that Burress had been invited to Foxborough, Mass., to work out for the AFC champions.
* The Minnesota Vikings have activated running back Adrian Peterson from the physically unable to perform list, with coach Leslie Frazier saying Peterson had done everything in his rehab that could be done working by himself. Peterson had major knee surgery on Dec. 31, and Frazier credited Peterson's hard work for the quick return.
* The Jacksonville Jaguars released veteran wide receiver Lee Evans and signed sixth-year receiver Demetrius Williams. Evans signed as a free agent with the Jaguars in April after he was released a month earlier by Baltimore.
* The Cleveland Browns' preseason-opening, 19-17 win in Detroit came at a significant cost. Wide receivers Mohamed Massaquoi (concussion) and Travis Benjamin, linebacker Scott Fujita, cornerback Dimitri Patterson (right ankle), tight end Jordan Cameron (back), and defensive tackle Scott Paxson (right knee) did not practice as the Browns resumed their training-camp schedule. All six are either starters or second-teamers on the depth chart.
Coach Pat Shurmur said, "It's hard to tell when they'll be back."
Massaquoi, Patterson, Cameron and Paxson each required help from Cleveland's training staff after on-field collisions. Shurmur would not reveal the injuries that Benjamin and Fujita suffered.
* The Green Bay Packers have signed veteran Cedric Benson. Benson left Cincinnati after spending four seasons with the Bengals, leading them in rushing each year. Green Bay finished 27th in rushing in 2011 despite going 15-1.
* Injured Chicago Bears middle linebacker Brian Urlacher expects to be ready for the regular-season opener against the Indianapolis Colts. Urlacher has left knee pain and has not practiced since July 31. "September 9 I'll be ready to play," he said. "I'm pretty sure. That's really all that matters to me.''
Urlacher sprained his medial collateral ligament and partially sprained the posterior cruciate ligament in the Bears' regular-season finale against Minnesota. There was no need for surgery, and he rehabbed the injury throughout the team's offseason workouts before returning to practice at the start of training camp.
"Preseason games and all these practices, I'd love to be out there, but I'm not going to put myself in jeopardy and miss the first game," Urlacher said. "I practiced the first 4 or 5 days and it felt pretty good and it got sore and a little swollen. So I'm taking some time off right now."
