Roster

49ers linebacker NaVorro Bowman recorded five tackles and a pass defended during San Francisco's 27-13 victory over Arizona in Week 17. It was just the fourth time this season Bowman with finished with less than eight tackles as he amassed 149 total stops, a career high.

The 49ers signed defensive back Craig Dahl to a three-year contract Saturday, finding an apparent replacement after Dashon Goldson received a five-year deal from the Buccaneers last week. Dahl, 27, spent the past four seasons with the Rams and registered 78 tackles and an interception in 2012. "It's a program I'm really familiar with, players and coaches I'm familiar with how they operate and the basis of what their team fundamentals are," he said.

Garrett Celek says he's aiming to replace Delanie Walker as the No. 2 tight end in the Niners' offense this summer. The Niners added rookie Vance McDonald and veteran Cameron Morrah as competition for the 6-foot-5, 252 pounder. Starter Vernon Davis and guard Alex Boone both think Celek has what it takes to do well with more reps in practice. "He's a great player," Boone told the official team website. "He's strong. He's tough. He's got great hands and he can run block. I think that's what makes a tight end really good. When he's out there, he can make good catches for you and he can always run block and help the run game. I think he does a good job with that."

49ers running back Anthony Dixon notched his second rushing touchdown of the season in Week 14 against the Dolphins. Dixon scored on a 1-yard scamper in the fourth quarter of the 27-13 win, capping off a 13-play, 83-yard scoring drive. He finished with 9 yards rushing on two carries and had a long of 8 yards.

Speaking on SiriusXM NFL Radio, Niners receiver Mario Manningham said he's feeling good and that his knee is getting stronger but has no timetable for his return. Manningham is hoping to be in the mix to help fill in for hurt Niners receiver Michael Crabtree but has to work his way back from a torn ACL first.

Knee - Questionable for start of training camp

The Sacramento Bee reports that new 49ers receiver Anquan Boldin is fitting in well with his new team. Boldin, acquired in a trade from Baltimore, is trying to prove he can help San Francisco get over the loss of Michael Crabtree (Achilles). The report said that in Tuesday's practice Boldin showed that it might not take long for him to pick up the offense and replace Crabtree as Colin Kaepernick's favorite target. "You got a good look at what he's been doing," coach Jim Harbaugh said. "He's picked up the system fast and making plays, big catches in tight areas."

49ers DB Tarell Brown left Sunday's NFC Championship Game against the Giants and did not return. He was struck by Dashon Goldson on a third down play late in the third quarter as they collided going for an interception.

49ers running back Kendall Hunter participated in team drills this week according to the official team website. Hunter is working his way back from a torn Achilles. "Kendall’s on track," was all coach Jim Harbaugh said. He's expected to be ready for training camp.

San Francisco defensive back Chris Culliver recorded his first interception of the year during Sunday's Week 5 contest against the Bills.

The Cleveland Browns have re-signed tight end Greg Estandia and defensive back Ray Ventrone. Estandia was claimed off waivers in September from Jacksonville.

LaMichael James promised the Sacramento Bee that he would be the Niners' punt return man this season. He tried the role last year but struggled in the preseason and never had the chance to do it. He also will work on kickoff returns while aiding in the run game behind Frank Gore. James also added 10 pounds of muscle to help him in his pass protection and stay healthy. He says he's the heaviest he's ever been in his life. "I'm way more explosive," he said. "I always felt like I was long-fast. I didn't really know how explosive I was. But I really worked hard on that -- just being more explosive."

He didn't commit to being ready for training camp but said that decision is up to trainer Jeff Ferguson.

Carradine is the fourth Florida State player taken in the draft's first 40 picks. The 49ers selection of Carrardine comes with some risk: the 24-year-old tore his ACL in a November loss to Florida. However, Carradine's rehab went well enough that he was able to participate in a pro day on April 20. Carradine reportedly ran a 4.93 40, an impressive number considering he was only five months removed from surgery. Before suffering the ACL injury, Carradine had been on a tear. During a three-game stretch in November where Florida State played Virginia Tech, Maryland and Florida, Carradine tallied a total of 27 tackles and three sacks. Despite missing Florida State's final two games last season, Carradine still managed to finish second on the team in both sacks (11) and tackles for a loss (13).

The man known as “Cowboy” wasn't going to miss the Super Bowl. But maybe Justin Smith should have sat out. Limited by a partially torn left triceps, the 49ers' defensive end struggled. Smith finished with three tackles -- with no quarterback hurries, hits or sacks. Now comes word, via Comcast Sports Net, that the 33-year-old Smith will undergo surgery this week and need three months of rehab.

Kaepernick has had a good offseason according to the coaching staff and looked especially poised and sharp in minicamp drills. "He's light years ahead of where he was last year," offensive coordinator Greg Roman said.

A bone-jarring tackler who can sometimes be too aggressive, former LSU free safety Eric Reid was taken by the 49ers with the No. 18 overall pick in the first round of the NFL Draft on Thursday. The defending NFC champs traded the 31st and 74th overall picks to the Cowboys to move up and snag Reid, who could replace Dashon Goldson. CBSSports.com's Rob Rang said Reid “might be the explosive hitter from the safety position in the 2013 draft, closing with the speed and physicality of a linebacker rather than a defensive back.” But Rang said Reid's greatest strength is also his biggest weakness. “He plays with nonstop aggressiveness and intensity, but he doesn't always control that hostility in a smart way,” Rang said.

The 49ers announced a contract extension for nose tackle Ian Williams.

As a young player he was very interested in his numbers. But after a recent offseason practice he told reporters the exact opposite when asked how his role could change with Michael Crabtree out for the next six months. "I don’t know what to expect, I’ll leave that up to the coaches," Davis said per the official team website. “All I can do is do my job and do what they ask me to do. I’m here to contribute in any form or fashion. ... I’m not worried about the numbers. I’m not worried about anything like that. I’m just here to do my job."

A.J. Jenkins has impressed thus far in offseason practices. The San Jose Mercury News says Jenkins had a great week after adding 10 pounds to his frame and working this offseason with quarterback Colin Kaepernick. Jenkins has looked more comfortable in the offense and seems to be playing fast without thinking about his assignment. "He made clutch catches for us when we were moving the ball," offensive coordinator Greg Roman said. "He just made plays and needs to continue that."

49ers linebacker Ahmad Brooks recorded his first career touchdown in Week 12 against the Saints.
