JACKSONVILLE, Fla. — The Jacksonville Jaguars will be without receiver Cecil Shorts III for the team’s season opener at Philadelphia.

Coach Gus Bradley downgraded Shorts from questionable to out Saturday. The team’s leading receiver in 2013, Shorts won’t even make the trip to Philadelphia.

Shorts was held out of practice Thursday and Friday after feeling tightness in his left hamstring.

It’s the latest injury for a fourth-year receiver who hasn’t been able to stay healthy since being drafted in the fourth round in 2011.

Shorts missed more than three weeks of training camp because of a strained right hamstring and sat out most of organized team activities with a calf injury. He also missed 11 games because of injuries during his first three NFL seasons.

Titans

DL Martin sidelined for Chiefs: In Nashville, Tenn., defensive lineman Mike Martin will miss Tennessee’s season opener at Kansas City on Sunday.

The Titans downgraded Martin from questionable to out Saturday.

Martin missed all preseason with an injured hamstring and had been limited all week in practice. The lineman was the Titans’ third-round pick in 2012 out of Michigan, and he has four sacks in 29 games in his career.

Vikings

Guard Fusco gets contract extension: In Minneapolis, the Minnesota Vikings have signed right guard Brandon Fusco to a contract extension.

The deal was done Saturday, just before the Vikings were scheduled to travel to St. Louis for the season opener Sunday.

Fusco was a sixth-round draft pick out of NCAA Division II Slippery Rock in 2011, who became a starter the next year, when Adrian Peterson rushed for 2,097 yards.

The Vikings kept the same offensive line intact for the third straight season. Fusco is the third of the five members who’ve signed long-term contracts within the past two years, along with center John Sullivan and right tackle Phil Loadholt.

49ers

Harbaugh: McDonald will play against Cowboys: In Santa Clara, San Francisco 49ers coach Jim Harbaugh said defensive end Ray McDonald, who was arrested in a domestic violence case last week, will play against the Dallas Cowboys on Sunday.

“As it stands now, yes he will play,” Harbaugh said Friday. “There are two principles woven together here. I feel the way the facts are, what’s known, he has the liberty to play the game.”

McDonald has been late for practice at least twice this week taking care of personal business, but Harbaugh said the seven-year veteran has been fine in practice.

Bengals

DT Still grateful for practice squad move: In Cincinnati, defensive tackle Devon Still understood why the Cincinnati Bengals couldn’t keep him on the roster.

With his injured hamstring and his daughter fighting cancer, the second-round pick has had a lot on his mind during training camp.

He’s grateful that the Bengals have kept him around anyway.

Still was waived as part of the final roster reduction a week ago. The Bengals signed him to the practice squad, which allows him to keep his medical insurance and get paid even though he won’t get to play in games.

His 4-year-old daughter was diagnosed with cancer in June. Still missed offseason practice time to be with her. Then he suffered a hamstring injury during the third preseason game.
