The 49ers acquired guard Laken Tomlinson on Thursday in a trade with the Detroit Lions for a draft pick, an NFL source confirmed to NBC Sports Bay Area.
The 49ers will send a 2019 fifth-round pick to the Lions in return for Tomlinson, the NFL Network reported.
Tomlinson, a first-round pick (No. 28 overall) in 2015 from Duke, was the final top pick of then-Lions general manager Martin Mayhew, who currently serves as 49ers senior personnel executive under general manager John Lynch.

Tomlinson, 25, has started 24 of the 32 NFL games in which he appeared during his two-year career. Most of his action came at left guard, where Zane Beadles has been lined up with the 49ers’ first-team offense. Tomlinson appears to in strong position to unseat Beadles in the 49ers' starting lineup for the Sept. 10 season opener against the Carolina Panthers.
Veteran Brandon Fusco has worked with the 49ers' starting unit at right guard.
All indications are that second-year guard Joshua Garnett is not expected to be available for the first half of the season. He is likely to open the season on injured reserve or injured reserve/designated for return. Garnett underwent arthroscopic surgery to repair meniscus cartilage after two weeks of training camp.
Tomlinson (6-foot-3, 312 pounds) ranked No. 64 of NFL guards last season, according to Pro Football Focus' grading system. Fusco, then with the Minnesota Vikings, was 58th, while Beadles was 68th.
