after a preseason knee injury to Zack Martin Youth Brett Maher Jersey
, the highest-paid guard in the NFL.Two people with knowledge of the diagnosis said Sunday that Martin has no structural damage in his hyperextended left knee and should be ready for the opener.Martin was injured in the second quarter of the Cowboys' 21-13 exhibition loss to Cincinnati on Saturday night. The people told The Associated Press that an MRI confirmed the Cowboys' belief that the injury wasn't serious. They spoke on condition of anonymity because there was no official update on Martin's status.The Cowboys open the season Sept. 9 at Carolina.Martin signed a six-year, $84 million extension with $40 million guaranteed during the offseason. The 27-year-old has made the Pro Bowl all four seasons in Dallas and started all 67 games, including three playoff games.The former Notre Dame standout was injured when he moved into the open field and bent down to block Bengals cornerback Dre Kirkpatrick on a run by Rod Smith. With Martin in the medical tent, the Cowboys finished their only touchdown drive with Dak Prescott's scrambling 6-yard throw to Terrance Williams"I was scared," Prescott said after the game. "I was just trying to get that touchdown and go check on him."Martin was a first-round draft pick in 2014 and became the club's first rookie All-Pro selection in 35 years while helping the Cowboys win the NFC East and just their second playoff since the last of the franchise's five Super Bowls during the 1995 season.The Cowboys had another injury scare with the offensive line earlier in training camp when center Travis Frederick saw a specialist in Los Angeles after a series of stingers. Frederick said he was cleared by doctors, although he likely will join Martin on the sideline for the rest of the preseason.While Martin was getting evaluated, Frederick and fellow offensive linemen La'el Collins and Tyron Smith waited just outside the medical tent along with 2016 NFL rushing leader Ezekiel Elliott."It was hard in that moment to think of all the possibilities of what could be going on right then with such a great player and such a great guy who's put in so much work to make sure his game is exactly where it is," Prescott said. "To see that wasn't good and it wasn't fun."Smith, another first-round pick and a five-time Pro Bowl selection Youth Maliek Collins Jersey
, has been battling back issues in recent seasons. Smith, Frederick and Martin have all made the Pro Bowl each of the past four seasons. Dak Prescott has a new No. 1 receiver and there's a fresh leading voice for the Dallas quarterback's blockers after the Cowboys traded for Amari Cooper and fired offensive line coach Paul Alexander during an open week that was much busier than normal.And there's little question about the message owner and general manager Jerry Jones is sending as the Cowboys try to keep a perfect home season intact to offset their winless road mark in a Monday night visit from the Tennessee Titans, who share the same record (3-4) and sense of urgency because of a three-game losing streak."We're more urgent because we've dug a hole here," Jones said on his radio show. "In order to really be where we want to be, which that (is) in the playoffs, then we've got to be pretty strong in our success here. We don't have time here. We don't have the room to wiggle here."The Cowboys gave Oakland their upcoming first-round draft pick for Cooper because the receivers simply haven't made the big plays the coaching staff and front office hoped would still be there despite the offseason release of Dez Bryant in a cost-cutting move.Dallas dumped Alexander in the middle of his first season and promoted former Cowboys lineman Marc Colombo because a front that has been among the NFL's best for several years simply hasn't been as good, with or without Travis Frederick. The four-time Pro Bowl center hasn't played and remains out indefinitely with a nerve disorder.Now it's time to see how some midseason upheaval, which included bringing retired former offensive line coach Hudson Houck out of retirement to help Colombo, translates to the field."I don't think it'll be that much of a change Youth La'el Collins Jersey
," right tackle La'el Collins said. "It's more so just us being able to do a lot of different things that we've done in the past, just kind of getting back to us playing at a high level and being more effective."The Titans are also coming off the bye week , preceded by a solid bounce-back game for Marcus Mariota after he was sacked 11 times — one shy of the NFL record — in a shutout loss to Baltimore.Mariota had a season-best 75 percent completion percentage (24 of 32) for 237 yards with a touchdown and an interception in a 20-19 loss to the Los Angeles Chargers — the second one-point loss on the current skid.Still, the Titans have the 30th-ranked offense and passing game in the NFL. And the Cowboys aren't much better at 28th and 29th."I think everybody across the offense has a sense of urgency," said Mariota, who turned 25 this week. "If we can carry that throughout the entirety of a game, I think we can be efficient. We can do well on third downs. We can score touchdowns."Some other things to know with the Titans and Cowboys set for a Monday night showdown:STILL IN THE HUNTBoth teams have been fortunate not to lose touch with the top of their divisions.The Titans have been overtaken by Houston's five-game winning streak in the AFC South, but are just one loss behind the Texans (5-3) in the loss column. The Cowboys have the same number of losses as Super Bowl champion Philadelphia (4-4) and can pull back even with the idle Eagles in the NFC East. Washington has a shot at a two-game cushion in a visit to Atlanta.THE RUNDOWNThe Titans are 19th in the NFL running the ball even with Derrick Henry, the 2015 Heisman Trophy winner Youth Antwaun Woods Jersey
, and Dion Lewis in the backfield.The Titans signed fullback Jalston Fowler to the roster after returning from their bye, and coach Mike Vrabel made it clear they want to run the ball better. Dallas star Ezekiel Elliott is coming off the second-worst game of his career, a 33-yard showing in a 20-17 loss to the Redskins.DEFENSIVE SHOWDOWNDallas is giving up just 17.6 points per game, second in the NFL and one spot ahead of Tennessee at 18.1. The Titans are the NFL's best inside an opponent's 20, while the Cowboys are second."It's going to be the battle of the red zone," Titans linebacker Wesley Woodyard said. "Bend, but don't break. That's been our mentality on defense."INCORPORATING COOPERCooper spent several days with Cowboys receivers coach Sanjay Lal in California. They went to a park in Oakland to work on routes, and Cooper had some video phone calls with Prescott to try to speed the process of learning one another.NO MORE GLOVEMariota said he is no longer wearing a partial glove that he was using to help with lingering numbness and tingling after injuring his elbow in the season opener.
