FOXBOROUGH, Mass. — Tom Coughlin came to New England to learn from the Patriots, not to rub their noses in the two championships he won from them.

The Jacksonville Jaguars’ executive vice president has been roaming the practice fields at Gillette Stadium, where they are working out with the Patriots in the days before their exhibition season opener on Thursday night.

“Obviously, they’re the world champions,” Coughlin said after practice Tuesday. “If you’re going to make a decision on who you’re going to work with, there is nothing better than working with Bill Belichick and the world championship team.”

It’s the sixth straight season the Patriots have held joint practices, and the first time the Jaguars have visited. Coughlin worked with Belichick as assistants to Bill Parcells with the Giants, the team Coughlin led to NFL titles in 2007 and 2011 by beating the Patriots.

• The Jaguars placed left tackle Branden Albert on the reserve/retired list, essentially ending his brief and baffling tenure with the team.

49ERS: Rookie linebacker Donavin Newsom suffered a concussion during practice but the team says he didn’t sustain any cervical spinal fractures.

FALCONS: Atlanta is holding out wide receiver Julio Jones in its preseason opener at Miami on Thursday night.

• The Falcons signed running back Kevin Taylor, the son of former Jacksonville Jaguars star Fred Taylor.

BENGALS: Coach Marvin Lewis missed practice for what the team called a minor health issue.

PACKERS: The team released defensive lineman Letroy Guion, ending a three-plus year tenure in Green Bay marked by off-field problems.

Guion was arrested on suspicion of driving under the influence in Hawaii in June.

PANTHERS: Quarterback Cam Newton will sit out the Panthers’ preseason opener against the Houston Texans on Wednesday night while he continues to battle soreness in his right throwing shoulder.
