Defensive linemen Sealver Siliga and Chris Jones avoided worst-case scenarios when they went down a couple weeks ago. Siliga suffered a sprained left wrist during an Aug. 5 joint practice against the Redskins, and Jones suffered a sprained ankle two days later in the preseason opener, according to a source. Siliga, who has worn a cast for the past two weeks, avoided a feared break, and Jones avoided a high ankle sprain.
