The 49ers are the fifth team to give Jonathan Cooper a chance after he arrived in the NFL as the No. 7 overall pick of the Arizona Cardinals in the 2013 draft.
Cooper, 28, caught the attention of the 49ers with his career-high 13 starts last season with the Dallas Cowboys. The 49ers signed him to a one-year, $4.95 million contract this week.
“We signed him to compete for one of the guard spots as a starter,” 49ers general manager John Lynch said Thursday at Stanford's pro day. “He played very well in our minds for Dallas last year and kind of resurrected his career. He’s battled injuries, but we really like the way he played, and we think he’s a very good fit for what we do. So we were pleased to add him.”
The 49ers plan to take it slowly this offseason with Cooper, who underwent surgery after tearing the medial-collateral ligament in his left knee during the final game of the season. The 49ers report for the offseason program in mid-April.
The 49ers are certain to have at least two new starters on the offensive line. Former New York Giants center Weston Richburg was signed to replace Daniel Kilgore, who was subsequently traded to the Miami Dolphins. Brandon Fusco, who started 16 games at right guard, signed with the Atlanta Falcons as an unrestricted free agent.
Laken Tomlinson has a chance to hold onto a starting job. Acquired shortly before the start of the regular season in a trade from the Detroit Lions, Tomlinson quickly moved into the starting lineup at left guard and started the final 15 games. Tomlinson was a first-round draft pick of the Lions in 2015.
“Laken played very well the longer he was there,” Lynch said. “I think people forget with Laken, he came here in Week 1. He was kind of force-fed. We didn’t have many options. But we saw a guy get better throughout the season. He’ll get his opportunity.”
Joshua Garnett, a first-round pick of the 49ers in 2016, spent last season on injured reserve due to an a knee injury sustained in training camp. The 49ers challenged Garnett to get in better physical condition. He has been cleared for football activity.
“Joshua Garnett has been working extremely hard, so he’ll be in that mix,” Lynch said. “He did a great job embracing the time he has last year to improve as a player. He remade his body and we're looking forward to see him get after it in the offseason.
“I think he’s excited about it. He’s feeling sexy, as he says.”
Erik Magnuson, 24, won a spot on the 49ers’ roster after signing as an undrafted rookie from Michigan. Magnuson could enter into the competition at guard. He displayed unique versatility in his first season, starting two games at right tackle before sustaining a season-ending foot injury. He can also serve as a backup center.
And, perhaps, the 49ers are not finished adding to the competition. The team owns the No. 9 overall selection, and Notre Dame’s Quenton Nelson could be on the radar in the unlikely event he is not selected within the top eight picks.
When asked if the 49ers could also add another player to the mix with a draft pick, Lynch answered, “We’ll see. We’re always looking to get better there.”
