The San Francisco 49ers signed veteran guard Jonathan Cooper to a one-year deal on Tuesday.
General manager John Lynch said in a statement that Cooper will compete for a starting job at guard with the 49ers.
"Having started 27 games in four NFL seasons, Jonathan brings great experience to the interior of our offensive line," Lynch said in the statement. "We look forward to him competing for a starting job at guard, while also bringing a veteran presence to our locker room. Jonathan is a welcome addition to our team."
Cooper started a career-high 13 games for the Dallas Cowboys in 2017, playing between Pro Bowl left tackle Tyron Smith and center Travis Frederick.
