COSTA MESA, Calif. — Los Angeles Chargers cornerback Jason Verrett was diagnosed with a torn Achilles tendon on Friday.

Verrett was injured while running during a conditioning test Friday morning. The team said Verrett will undergo more testing on his Achilles on Saturday, but it is expected that he will miss the season.

  Verrett is possible out again. That being said, the Chargers have built depth and talent to help mitigate the loss. But they can’t afford more injuries

The Cardinals, Broncos, Chargers and Vikings open training camp on Friday, meaning all 32 NFL teams are now camping. Meanwhile, the Titans gave Taylor Lewan the richest deal for an offensive lineman in NFL history, and Drew Brees demolished a poor pinata.

FOXBOROUGH, Mass. — New England Patriots tight end Rob Gronkowski said in June that he hoped to land an upgraded contract, but he relayed Thursday that he never considered holding out from training camp to get it.

“No, it hasn’t even came close to considering that. Not even one bit,” he said after the team’s first practice of camp. “What I can do, though, is keep preparing, keep showing up every day, keep doing what I’ve got to do to get better.”

New York Jets cornerback Rashard Robinson, who was arrested last December and charged with marijuana possession, was suspended four games by the NFL for violating its substance-abuse policy, the team announced Wednesday.

Robinson, hardly a lock to make the 53-man roster, is eligible to return Oct. 1, the day after the Jets play the Jacksonville Jaguars in their fourth game. He’s allowed to practice and play in preseason games.

The Jets acquired Robinson last year from the San Francisco 49ers at the trading deadline, dealing a 2018 fifth-round pick. He played in only six games for the Jets, a total of 20 defensive snaps. He was inactive for the final two games.

In December, Robinson was arrested in New Jersey after police allegedly discovered marijuana-laced candy in his car. The case still is pending.

Robinson, 23, has a history of off-the-field issues, dating to his college days at LSU. In 2015, he was arrested and thrown out of school after breaking into a teammate’s apartment.

He sat out the 2015 season, but wound up becoming a fourth-round pick of the 49ers in 2016. He played 22 games, including 13 starts, but he fell out of favor with their new regime.

The Jets are waiting for word on wide receiver Robby Anderson, whose case still is under review by the league under its personal-conduct policy, a league spokesman told ESPN on Wednesday. He was arrested twice in a nine-month span. All charges were dropped, except for one; he pleaded no contest last month to reckless driving, a misdemeanor in Florida.
