CLEVELAND (AP) -- Barkevious Mingo's comeback from a strange injury is nearly complete.
The first-round draft pick who sustained a bruised lung last month returned to practice in a limited role Monday, a significant step in his recovery from the mysterious injury.
Mingo was injured in an Aug. 15 exhibition game against Detroit and hospitalized for two days at The Cleveland Clinic. The No. 6 overall pick took part in position drills, but did not have any contact during the 30 minutes of practice open to reporters. It's doubtful Mingo took part in any of the 11-on-11 team drills
Mingo's status for Sunday's season opener against the Miami Dolphins is still to be determined. The 6-foot-5, 240-pounder will likely undergo more testing before he can be cleared to play. He experienced shortness of breath and said he spit up some blood while he was on the sideline against the Lions.
He was in the locker room after practice, but a team spokesman said he would not talk to the media until Friday.
Browns coach Rob Chudzinski was not available Monday.
Mingo was restricted to riding a stationary bike, some running and light weightlifting last week, so his appearance on the field is a sign he's made good progress.
"It's good," linebacker D'Qwell Jackson said. "The main thing is his health. He's dealing with something that I never had experience with and a lot of other guys haven't. So you want to be overcautious with something like that. It's good to see him moving, and whenever we get him back he's going to be full steam ahead. He's a smart guy and he's done everything right so far."
Mingo doesn't remember taking a hit that could have caused the unusual injury.
The Browns plan to use him as an outside pass rusher whenever he returns.
"He's ready to go," Jackson said. "He was a first-round pick. He wants to be out there to show guys how good he can rush off the edge. We know how good he's going to be and how good he is right now. The good thing about this team, we have guys who can step up while he's out, so it's no rush for him to come back."
CLEVELAND -- The Browns are bringing in Pro Bowl kickers Dan Carpenter and Billy Cundiff for tryouts on Tuesday.
After terminating veteran Shayne Graham's contract and releasing rookie Brandon Bogotay over the weekend, the Browns don't have a kicker less than one week before their opener against Miami.
Carpenter was released by Miami, Arizona and the New York Jets last month.
Cundiff was with the Browns in 2009, filling in when Phil Dawson was sidelined with a strained calf. Cundiff kicked the winning field goal as the Browns beat Buffalo 6-3 in Week 5. Cundiff was also cut by the Jets this summer.
The Browns have been looking for a kicker since deciding not to re-sign Dawson, who left after his 14th season with Cleveland and is with San Francisco.
Graham went 3 for 3 during the exhibition season and hasn't been ruled out as a candidate.
CINCINNATI -- The Bengals have signed defensive tackle Geno Atkins to a five-year contract extension, locking up one of their best defensive players through 2018.
The All-Pro tackle, a fourth-round pick in 2010, was entering the final year on his original deal. He made the Pro Bowl each of the last two seasons. Atkins had 121/2 sacks last season, the most by any interior lineman in the NFL.
Cincinnati has spent more than $180 million since the end of last season keeping their team intact. The Bengals have reached the playoffs each of the last two seasons as a wild card, only to lose to Houston in the first round.
Atkins is the 12th Bengals player to get either a new contract or an extension since the end of last season.
ALLEN PARK, Mich. -- The Detroit Lions say they have claimed safety DeJon Gomes on waivers.
The team announced the move Monday, six days ahead of its regular season opener against the visiting Minnesota Vikings.
The Washington Red Skins announced Gomes' waiver Saturday.
He played college ball at Nebraska and was a fifth-round pick by Washington in 2011.
ASHBURN, Va. -- So much for those last-minute "concerns." RG3 is starting Week 1.
Washington Redskins coach Mike Shanahan said Monday that Robert Griffin III will be under center for next week's Monday night opener against the Philadelphia Eagles.
Griffin was cleared last Thursday to play in Week 1 by his surgeon, Dr. James Andrews. However, Shanahan said at the time that Andrews also had unspecified "concerns."
The coach said he addressed those concerns with Griffin and Andrews on Sunday. Shanahan declined to say what the concerns are: "You'll have to trust us."
The start marks a remarkably expedited return for last year's NFL Offensive Rookie of the Year, who had major knee surgery just days after he was injured in the Redskins' playoff loss in January to Seattle.
LAKE FOREST, Ill. -- Chicago Bears star Brandon Marshall says his surgically repaired hip is structurally sound heading into the season opener this week.
The Bears meet the Cincinnati Bengals, and the Pro Bowl receiver says he's in good shape after missing the preseason finale. He had an excused absence for that game against Cleveland and was examined over the weekend.
He was back with the Bears on Monday.
Marshall says the joint is "in amazing shape" after having his third hip surgery in four years. The arthroscopic procedure followed a season in which Marshall set franchise records for catches (118) and yards receiving (1,508).
INDIANAPOLIS -- The Andrew Luck that shows up Sunday afternoon won't be the same one Colts fans were used to seeing last season.
He's more confident. He's more relaxed. He's a more vocal leader.
Yes, it's a natural progression for a second-year NFL quarterback, particularly one that has been as hyped as Luck was coming out of college.
But for Luck and his teammates, this is also a necessary transformation if Indianapolis is going to take that next big step.
It's not as if Luck was bad in 2012. He had one of the most productive rookie seasons in NFL history, and he presided over one of the biggest turnarounds, from 2-14 to 11-5 and the playoffs.
He just wants to improve enough to make the Colts better in 2013.
