The Lions have made a trade with Seattle to bring guard Rob Sims to Detroit, according to a twitter report from ESPN’s Adam Schefter. The Lions will send a fifth-round pick to the Seahawks.

The trade will fill the big, gaping hole at left guard and help solidify the offensive line.

Sims started 14 games for the Seahawks in 2009. He became expendable with the arrival of new coach Pete Carroll and a new system.

Sims was a fourth-round pick (128th overall) by Seattle in 2006. He played at Ohio State.

It’s the third major trade of the offseason by Lions general manager Martin Mayhew. He also traded Cleveland for DT Corey Williams and Atlanta for CB Chris Houston.
