STATELINE, Nev. - Quarterback Trent Dilfer, who played the last of his 13 NFL seasons with the San Francisco 49ers last year, said Wednesday he’ll make a formal announcement in the coming days that he is retiring from football.

Dilfer, who won a Super Bowl with the Baltimore Ravens, said a recent injury to his Achilles’ tendon helped make up his mind.

“I was going to retire anyway. This just gives clarity to the situation,” he said during a news conference for American Century Celebrity Golf Championship that begins Friday at Lake Tahoe.
The 36-year-old Dilfer said he’s been considering some different options post-football but declined to elaborate.

“I think in the next few days there will be a formal announcement on all those things,” he said. “I think everybody I’ve talked to says (camaraderie is) the hardest thing to get away from, just the locker room, just being around the guys each day, the routine of the season. But I knew this time was coming, and here it is.”
