The Rams' first draft choice, defensive back Jerry Gray of Texas, was their last draft choice to agree to contract terms Thursday.
Gray, who has missed nearly three weeks of training camp since other rookies reported, was expected to practice this morning before the squad goes to La Jolla to scrimmage the San Diego Chargers.
Gray, described as "a trained killer" by Coach Barry Switzer of Oklahoma, was a two-time All-American safety. The Rams plan to play him at cornerback.
He is a 6-foot 1-inch, 183-pounder with a speed rating of 4.4 seconds for 40 yards.
Gray's signing leaves only holdout Eric Dickerson and unsigned nose tackle Greg Meisner missing from training camp.
In other negotiations, the Rams were about to waive veteran reserve safety Ivory Sully when trade talks with Tampa Bay came back to life. Sully had asked to be traded or released.
