SANTA CLARA — Offensive lineman Jonathan Martin, who had a tumultuous departure from the Miami Dolphins last October amid a bullying scandal, made the 49ers when the team trimmed its roster to the NFL’s 53-man limit on Saturday.

Martin is getting a fresh start following a scandal in which he accused teammate Richie Incognito of bullying.

An NFL investigation determined Incognito and two other Dolphins offensive linemen engaged in persistent harassment of Martin.

Martin started all four of San Francisco’s preseason games at right tackle in place of injured regular Anthony Davis. He also has value at other line positions and has fit in well with his new team this summer.

“Jonathan is another example of someone who has really earned the position, and we’re very fortunate to have him and excited about it,” 49ers coach Jim Harbaugh said Saturday. “He’s mainly played tackle, but he has the ability to play guard and going forward that will be something that he’ll continue to learn and be good at. I feel very good about it. He’s done an excellent job of getting the job done.”

Martin joins rookies Marcus Martin and Dillon Farrell as new additions to a San Francisco line that parted ways with Adam Snyder, a nine-year veteran with 87 career starts. Snyder was expected to be a top backup at center and both guard positions this season.

Snyder has 87 starts, including 75 with the 49ers, who drafted him in the third round in 2005. He returned to the team last season after spending one year in Arizona, starting four games at left guard in place of the injured Mike Iupati.

The 49ers also are without incumbent starting right guard Alex Boone, a holdout all summer as he seeks a new contract.

Also among those released were safeties C.J. Spillman and Bubba Ventrone, wide receiver Kassim Osgood and long snapper Kevin McDermott. Also released by the 49ers were: offensive linemen Carter Bykowski, Al Netter, Michael Philipp and Ryan Seymour.


San Francisco 49ers linebacker Aldon Smith has apologized to the organization and its fans after receiving a nine-game suspension from the NFL for a series of off-field legal issues.

In a statement released through the NFL Players Association on Saturday, Smith said: “I apologize to my teammates, coaches, the entire 49ers organization and 49ers fans for not being able to contribute on the field for the next several weeks. .

The NFL announced Smith’s suspension Friday.

The league said in a statement Smith had violated its substance abuse and personal conduct policies.

Smith missed five games last season to undergo treatment at an in-patient facility following his DUI arrest Sept. 20.

In November, he pleaded not guilty to three felony counts of illegal possession of an assault weapon, stemming from a June 2012 party at his home.

Smith also was arrested April 13 at Los Angeles International Airport for allegedly making a bomb threat. No charges were filed.
