New England Patriots running back Dion Lewis needs a second surgery on his injured left knee and offensive lineman Sebastian Vollmer could miss the season with injury, according to media reports

Lewis, who tore his left ACL on Nov. 8, will need surgery to clean up his left knee, according to the Boston Globe. The 5-foot-8, 195-pound back had 234 yards and two touchdowns rushing, as well as 36 receptions for 388 yards and two touchdowns in seven games last season.

Vollmer has been on the physically unable to perform list with a hip injury and could stay there, according to an report. Vollmer also had off season shoulder surgery, according to the report.

Also, guard Shaq Mason reportedly has a broken hand, according to the Globe report.

JETS: Todd Bowles declines to say whether Geno Smith remains the New York’s No. 2 quarterback behind Ryan Fitzpatrick or if Bryce Petty has surpassed him on the depth chart.

The Jets coach said earlier in training camp there was no change in the pecking order, but Petty had a strong showing in New York’s 22-18 loss at Washington on Friday night. Meanwhile, Smith struggled in the game and appeared to perhaps lose his stranglehold on the backup job.

DOLPHINS: Center Mike Pouncey has been sidelined by a left hip injury that could force him to miss the season opener.

Pouncey was hurt in Friday’s exhibition game at Dallas, and he’ll likely sit out the final two exhibition games, Coach Adam Gase said Sunday.

Rookie running back Kenyan Drake, who has been sidelined with a hamstring injury, will again be out this week, Gase said.

CARDINALS: Tyrann Mathieu, Justin Bethel and Frostee Rucker practiced for the first time this training camp and Arizona Cardinals Coach Bruce Arians said “there’s no doubt” all three will be ready for the Sept. 11 season opener.

Mathieu, an All-Pro safety last season who is coming back from surgery to repair a torn right ACL, participated in several plays 11-on-11 drills with the first unit, surprising himself and his teammates with how much he was able to do.

“I’ve got my swag back,” he said. “I feel good, confident.”

Bethel, a cornerback, is returning from foot surgery and defensive lineman Rucker had a foot injury that might have been related to ankle surgery.

GIANTS: Coach Ben McAdoo isn’t going to shake things up despite dismal performances in the first two preseason games, both losses.

Speaking a day after dropping a 21-0 decision to the Bills in Buffalo, McAdoo said that some backups are going to get chances to show what they can do this week.

The offensive line has to be the first-year coach’s biggest concern. It failed to generate much of a running game last season and the Giants didn’t do anything in the offseason to improve it.

COWBOYS: Dallas had its first workday at its new practice facility – part headquarters, part spa, part museum with amenities the players probably couldn’t have imagined at aging Valley Ranch.

“I mean, words can’t describe it,” Witten said about the site about 30 miles north of Dallas. “It’s an unbelievable facility.”

Historical displays from a franchise with five Super Bowl titles are scattered through the football wing and the adjacent headquarters, an office building with a view of the outdoor practice fields on one side.
