    Place the roast directly on the grill grates. Insert the probe into the center of one roast half, avoiding the bones and any large pockets of fat. Close the lid and cook for 30 minutes, then reduce the Traeger temperature to 300°F and continue roasting until the internal temperature reaches 125°F for medium-rare, or your desired temperature, another 30-40 minutes (the temperature will continue to rise slightly after the roast is removed from the grill).
