Washington Redskins wide receiver DeSean Jackson reportedly suffered a separated right shoulder on Thursday and could miss a few weeks.

Jackson suffered a Grade 2 separation during a joint practice with the Houston Texans, according to Dianna Marie Russini of ESPN. Multiple reports indicated Jackson ran into a blocking sled.

Also, veteran cornerback DeAngelo Hall is expected to be out a week or so with a groin injury, ESPN reported.

Hall is the fourth Redskins cornerback to get hurt in camp. Tevin Mitchel (torn labrum) was waived, Bashaud Breeland (knee) is out 4-6 weeks and David Amerson (shoulder) will miss a few days.

—Arizona Cardinals wide receiver Michael Floyd underwent surgery after injuring his fingers on his left hand during practice on Wednesday.

The Cardinals also announced Thursday that they waived guard John Fullington, who has a knee injury, and released tight end Ted Bolser.

Floyd tweeted Thursday that the procedure went well and thanked fans for their support. He also posted a photo on Instagram from a hospital bed with his left hand and forearm bandaged.

According to reports on Wednesday, Floyd suffered three dislocated fingers and was expected to miss 3-5 weeks. It’s unclear after the surgery whether he will be able to return in time for the Cardinals’ season opener on Sept. 13 at home against the New Orleans Saints.

—Cleveland Browns linebacker Barkevious Mingo underwent arthroscopic procedure to repair torn meniscus in a knee that likely will sideline him for about a month.

Mingo did not practice with the team on Wednesday after feeling stiffness in the knee. An MRI later in the day confirmed the tear.

The recovery and rehab likely will force Mingo to miss the Browns’ four preseason games, but he could return for the season opener on Sept. 13 against the New York Jets.

—Atlanta Falcons running back Devonta Freeman suffered a right hamstring strain in practice on Thursday.

“Hopefully, for him, it’s a quick turnaround,” first-year coach Dan Quinn said. “He’s such a passionate competitor. You can see how disappointed he was not to be able to finish today. So hopefully, we’ll get him back out here soon.”

Rookie running back Tevin Coleman, who is competing with Freeman for the starting job, has missed the past two days with a hamstring injury as well.

—The Oakland Raiders removed running back Trent Richardson from the non-football injury list on Thursday.

Richardson had not practiced since reporting to camp overweight last Friday.

“He came back very close to the weight, which was a pretty ambitious goal to get to,” coach Jack Del Rio said. “He’s down in the low 220s. That’s what we asked of him. That’s where he was. … He’ll have a chance to come out here and show what he’s really capable of.”

Richardson, a former first-round pick who is on his third team in four years, will battle for a roster spot behind Latavius Murray and Roy Helu Jr.

—Wide receiver Kevin White, the Chicago Bears’ first-round draft pick who has been out of training camp with a shin injury, reportedly will resume running next week.

It’s still possible White could start the season on the physically-unable-to-perform list due to the shin splints, Ian Rapoport of NFL Media reported Thursday.

White was injured near the end of organized team activities in June and did not practice during minicamp.

—Indianapolis Colts outside linebacker Robert Mathis will not see game action until late September or early October.

That’s the projection of Colts’ owner Jim Irsay, who echoed the sentiment of coach Chuck Pagano that Mathis, 34, won’t be rushed back from the torn Achilles tendon that kept him out all of last season.

The Colts claimed injured rookie cornerback Tevin Mitchel off waivers on Thursday and waived safety Robert Smith.

—The Tampa Bay Buccaneers signed quarterback-turned-linebacker Sammuel Lamur.

The 6-foot-5, 225-pound Lamur was a quarterback at Kansas State and also in the Arena Football League with the Tampa Bay Storm.

Lamur filled an opening on the Buccaneers’ 90-player roster created after the team waived long snapper Courtland Clavette. Lamur’s brother, Emmanuel, is a linebacker for the Cincinnati Bengals.

—The Denver Broncos signed nose tackle Sione Fua and waived punter/kicker Karl Schmitz.

Fua, a five-year NFL veteran, played in two games for the Broncos in 2013 and had had one tackle.

Schmitz was waived after punter Britton Colquitt reached agreement on a contract with a salary reduction for the 2015 season.

—The New England Patriots signed offensive lineman Mark Asper and tight end Mason Brodine while releasing offensive lineman Harland Gunn.

Asper, 29, a sixth-round draft pick by the Buffalo Bills in 2012, played in one game for the Jacksonville Jaguars in 2012 and six games for the Bills in 2013. He also has spent time on the practice squad of the Minnesota Vikings, New York Giants, Denver Broncos and Miami Dolphins.

Brodine, 27, spent the 2012 and the 2013 seasons on the St. Louis practice squad and was on injured reserve last season. Gunn, 25, was claimed off waivers by the Patriots from Atlanta on Monday.

—The Buffalo Bills signed running back Bronson Hill and released defensive end Erik Williams.

Hill, a 5-foot-10, 215-pound rusher from Eastern Michigan, is an undrafted rookie. He played in 42 games for Eastern Michigan, rushing for 2,357 yards and 11 touchdowns.

Williams is a 6-3, 270-pounds rookie from Bethune-Cookman.

—The San Francisco 49ers waived injured offensive lineman Ben Gottschalk on Thursday.

Gottschalk signed with San Francisco on June 6 after he was waived a week earlier by the Tampa Bay Buccaneers.

The 23-year-old Gottschalk originally signed with the Kansas City Chiefs as an undrafted free agent in May 2014 and was waived Aug. 27. He then joined the Chiefs’ practice squad on Sept. 1 but was waived eight days later. On April 8, Gottschalk signed with the Buccaneers but lasted less than two months before he was waived again.
