SANTA CLARA – One of Greg Roman's college teammates will become the new general manager of the Jacksonville Jaguars, raising the possibility the 49ers' offensive coordinator also will find his way to northern Florida.

Roman and David Caldwell, who is leaving the Atlanta Falcons as their director of player personnel, were roommates at John Carroll University in the early 1990s. They also were young assistants on the Carolina Panthers' staff in 1996.

Roman acknowledged his friendship with Caldwell, but he said he wouldn't be contacting his former teammate anytime soon.

"Dave's in Atlanta, and we might end up playing them, so not really talking to Dave right now," he said.

The 49ers' assistants had a one-week window last week to interview for coaching vacancies. None of them, including Roman, received an interview request. Roman could interview for one of the remaining five coaching vacancies after Saturday if the 49ers lose. A 49ers win means the next time he can interview is after the NFC Championship Game.

The Jaguars retained coach Mike Mularkey but gave his assistants permission to interview for other jobs, an indication Mularkey could be replaced.

Another Roman chum from John Carroll, Tom Telesco, is a finalist for the San Diego Chargers' general manager job, which reportedly will be decided today.

If Roman leaves, the 49ers' top internal candidates to replace him would be quarterbacks coach Geep Chryst, receivers coach John Morton and offensive-line coach Tim Drevno.

Stanford's Pep Hamilton also would be a possibility.

Candlestick debut – Billy Cundiff, who is battling David Akers to be the 49ers' kicker Saturday, took his first kicks inside Candlestick Park during a practice session Monday.

"We didn't actually have that much wind, so I don't think I got the full taste of Candlestick," he said Tuesday. "But I thought it was good. It gave me a chance to test out the field conditions and get the visuals of the stadium and things like that."

Cundiff, who kicked during the day, said he's been getting pointers from punter Andy Lee and long snapper Brian Jennings, who said the field tends to get more slick at night, which is when the 49ers will be playing the Green Bay Packers.

That's good, Cundiff said, because the 49ers' practice fields have been wet as well.

All aboard! – Green Bay quarterback Aaron Rodgers, who once promised to bring a convoy of Packers backers from his hometown of Chico when he played the 49ers, said he's had a hard time securing tickets this week.

"Most people know they're on their own this week," Rodgers said on a conference call. "Family first."

Rodgers said he still spends part of his offseason in his hometown.

• Starting linebacker Ahmad Brooks was out of his no-contact, black practice jersey. But three fellow starters – linebacker Aldon Smith (shoulder), cornerback Tarell Brown (knee) and fullback Bruce Miller (shoulder) – remained in black jerseys Tuesday.

• The 49ers signed ex-Raiders draft pick Nate Stupar to the practice squad. Stupar, a linebacker from Penn State, was a seventh-round draft pick by Oakland in 2012.
