The Kansas City Chiefs’ unlucky season with injuries collected another chapter Friday when the team announced that running back Joe McKnight suffered a ruptured Achilles tendon.

He definitely will not play in Monday night’s game against New England and he appears headed for surgery that will end his 2014 season.

The injury occurred during Thursday afternoon’s practice and he becomes the third Chiefs player this season who suffered a ruptured Achilles. Inside linebacker Derrick Johnson and defensive end Mike DeVito both went out in the season opener and they are now on the injured-reserve list.

—Minnesota Vikings linebacker Chad Greenway, who has played in 115 consecutive games, was ruled out of Sunday’s game against the Atlanta Falcons.

He also has 90 straight regular-season starts, the longest of any linebacker in the NFL. Greenway, who played through a broken wrist for much of last season, suffered a broken hand in the Week 2 loss against the New England Patriots but played last Sunday against the New Orleans Saints. During that game, he suffered a rib injury that forced to leave.

Coach Mike Zimmer said Gerald Hodges and others will help fill Greenway’s void.

Tight end Kyle Rudolph, who has an abdomen/groin issue that is expected to keep him out for at least the next few weeks, has been formally ruled out for Sunday. Cornerback Josh Robinson was listed as questionable.

—Miami Dolphins quarterback Ryan Tannehill said he has moved past the controversy after coach Joe Philbin was noncommittal on the team’s starter earlier this week.

“It’s done,” Tannehill said after practice in London in preparation for Sunday’s game against the Oakland Raiders. “It’s something we faced during the week, and it’s done. Now we’re just getting ready to play. I’m excited to be here in London.”

During the week, Philbin refused to say for sure that Tannehill would be the starter. On Wednesday, Tannehill confirmed that he would start and seemed upset that he had to answer such questions.

—The Washington Redskins, who have already lost quarterback Robert Griffin III, tight end Jordan Reed, nose tackle Barry Cofield, cornerback DeAngelo Hall and left guard Shawn Lauvao for at least a game apiece, might have dodged more bad news with two-time Pro Bowl left tackle Trent Williams.

Williams, who exited Thursday night’s 45-14 loss to the New York Giants with a strained right knee, didn’t need the expected MRI on Friday. “It’s patellar inflammation,” coach Jay Gruden said. “He should be OK (for next Monday’s game against Seattle). That’s a relief.”

The news was the opposite on the other Trent. Reserve safety Trenton Robinson will probably miss a few weeks with a left high ankle sprain. As for tight end Niles Paul, he suffered a concussion on his final catch against the Giants when he was slammed by safety Quentin Demps and didn’t return. Gruden said Paul has entered the NFL’s concussion protocol and is day to day for the Seahawks.

—Green Bay Packers linebacker Clay Matthews, who has made progress since leaving last week’s game with a groin strain, was listed as probable against the Chicago Bears on Sunday.

Matthews took part in practice on a limited basis Wednesday and Thursday. The Packers did not practice Friday.

“Yeah, so far, so good,” coach Mike McCarthy said Friday.

—Detroit Lions wide receiver Calvin Johnson was back at practice Friday after missing the previous two days with an ankle injury he suffered last Sunday against Green Bay.

Johnson was adamant all along that he was going to play Sunday against the New York Jets. But when Megatron misses practice, it is difficult to ignore. Johnson has 19 catches for 329 yards and two touchdowns this season.

The news wasn’t all good for the Lions on Friday as tight end Joseph Fauria missed practice for a second straight day after injuring his ankle in a non-football activity.

—After working out the previous two days, Atlanta Falcons wide receiver Harry Douglas was limited Friday and is listed as questionable for Sunday’s game at Minnesota.

Douglas is expected to play.

Listed as probable Friday are wide receiver Roddy White (hamstring), wide receiver/return specialist Devin Hester (ankle), linebacker Prince Shembo (calf) and running back Antone Smith (hamstring).

—The Baltimore Ravens signed third-year wide receiver Deonte Thompson to the practice squad Friday after he passed through waivers.

This was the fourth transaction the Ravens have made with Thompson within the last week. He spent the first two games of 2014 on the roster. The team waived him six days ago. Thompson, 25, has been with the Ravens for the last three years. He made the team as an undrafted free agent in 2012 and then he spent all of last season on the active roster. Thompson has 15 career catches for 147 yards.

To make room on the practice squad, the Ravens cut defensive lineman A.J. Pataiali’i.

—The New England Patriots signed defensive lineman Ben Bass to the practice squad on Friday.

Bass, 24, was acquired by the Patriots in a trade with the Dallas Cowboys in exchange for defensive back Justin Green on Aug. 15. The 6-foot-5, 295-pounder Bass was released by the Patriots on Aug. 26. He originally joined the Cowboys in 2012 as a rookie free agent out of Texas A&M on May 14, 2012 and spent most of that season on the Cowboys’ practice squad before being activated to the 53-man roster on Nov. 13, 2013.

The Patriots also released offensive lineman Chris Martin from the practice squad.

— Although New Orleans Saints center Jonathan Goodwin took part in practice Friday, he was still listed as questionable for Sunday’s game against the Dallas Cowboys.

Cornerback Patrick Robinson was added to the injury report as questionable because of a hamstring issue. Three players were declared out for the game — running back Mark Ingram (hand), safety Marcus Ball (hamstring) and fullback Erik Lorig (ankle).

Listed along with Goodwin as questionable are linebacker David Hawthorne (ankle/knee) and tight end Ben Watson (groin). Watson and Goodwin were injured in last Sunday’s win over the Minnesota Vikings.
