ST. LOUIS (AP) — The St. Louis Rams picked their third offensive lineman of the NFL draft, selecting Andrew Donnal of Iowa in the fourth round on Saturday. The Rams have just two starters back on the line, guard Rodger Saffold and tackle Greg Robinson.

They picked Rob Havenstein of Wisconsin in the second round and Jamon Brown of Louisville in the third. The 6-foot-7, 305-pound Donnal started every game at right tackle as a senior and was honorable mention All-Big Ten by league coaches. He made no starts in 2013 but played at guard and tackle.
