A new but familiar face could be joining the San Francisco 49ers quarterback competition between Alex Smith and Colin Kaepernick.

Coach Jim Harbaugh confirmed after Sunday’s practice that former Vikings quarterback Daunte Culpepper will work out today.

“It’s an opportunity to look at a veteran quarterback, put a third guy on the roster who’s been there before and has had game experience,” Harbaugh said. “We’ll see where he’s at physically, see where he’s at mentally and emotionally. I’m looking forward to a good workout.”

Culpepper played last season with the United Football League’s Sacramento Mountain Lions, his first year out of the NFL since joining the Vikings as a 1999 first-round draft pick.

Culpepper, 34, was a three-time Pro Bowler while with the Vikings from 1999-2005. After a serious knee injury, he bounced to the Miami Dolphins in 2006, the Oakland Raiders in 2007 and the Detroit Lions in 2008-09. Last year in the UFL, Culpepper threw 10 touchdown passes and 12 interceptions.

“All positions are still competing,” Harbaugh said. “We’ll determine (the starter based) on who’s practicing better, who’s playing better.”

Smith, who remains atop the 49ers’ depth chart, completed 2 of 7 passes for 10 yards and was sacked twice in Friday night’s opener against New Orleans. Kaepernick played the remainder of that 24-3 defeat.

Harbaugh said Saturday the quarterback situation hasn’t had a chance to become “clear-cut” yet. Smith did not start practicing until nearly a week into training camp because of league rules regarding re-signed players.

“I mean, he hasn’t seen any of us play,” Smith said of Harbaugh. “Why wouldn’t it be an open competition and why wouldn’t he want to see us play football and then go from there?”

Umenyiora ends stalemate: A miffed Osi Umenyiora is returning to the New York Giants without a new contract.

In a Sunday evening email to the Associated Press, the two-time Pro Bowl defensive end said he plans to practice today at training camp and that he will play this season under the terms of his current contract.

Umenyiora said the Giants offered to put incentives in his contact, which would pay him $7.1 million over the next two seasons, but he rejected them.

“No deal has been reworked,” Umenyiora said. “What has been offered has been unacceptable and shows they don’t really respect the fact I sacrifice my health for the franchise. I will play under my current deal because I love and respect my coaches, my teammates, the fans, and myself. Not for those incentives.”

Umenyiora, 29, didn’t say how much money the team offered in incentives.

The nine-year NFL veteran hasn’t practiced since reporting to training camp July 30, a day late.

Giants’ Tynes ailing: The Giants might be welcoming more than Umenyiora to training camp today. They could be getting a new kicker, too.

Lawrence Tynes bruised his right thigh in Saturday night’s exhibition loss to the Carolina Panthers, and coach Tom Coughlin said the veteran kicker will be spending a lot of time with the team’s medical personnel this week.

“I’m not going to predict how long he’ll be out,” Coughlin said. “He’ll be a full-time participant in the training room, that’s for sure.”

Coughlin was not sure whether the Giants would sign a kicker this week, but it seems unlikely that Tynes will be able to play next Monday against Chicago. He was on crutches after the game, the result of being run into on a blocked field goal.

Saints’ Porter says knee OK: New Orleans starting cornerback Tracy Porter returned to practice for the first time since training camp opened and said his surgically repaired left knee isn’t bothering him.

Porter has been recovering from offseason microfracture surgery that is designed to improve the condition of cartilage padding his knee joint. He said he is ahead of schedule.

Also at practice Sunday night were receivers Marques Colston and Robert Meachem. Colston was sidelined by swelling around his surgically repaired right kneecap for more than a week, and Meachem left Friday night’s exhibition opener against San Francisco because of low back strain.

Redskins cut Graham: The duel between the kicking Grahams lasted all of one preseason game.

The Washington Redskins cut Shayne Graham, leaving incumbent Graham Gano as the only kicker at training camp.

Graham is the third-most-accurate kicker in NFL history, but he shanked a 29-yard field-goal attempt and missed a 49-yarder in Friday’s exhibition win over Pittsburgh.
