Hall Davis is a former St. Louis Rams fifth-round pick who also has been with the Washington Redskins and the Tennessee Titans but never played in a game. At 6-foot-6 and 262 pounds, he'd play outside linebacker for the Packers. As a senior at Louisiana-Lafayette, he was a stand-up player who had three sacks.
Robert Rose (6-foot-4, 294 pounds) is an athletic defensive end who went undrafted out of Ohio State in 2010. He was signed by the Seattle Seahawks after the draft before being cut and then spending time with the Miami Dolphins on their practice squad last year. He was among their final cuts this summer. He ran a 4.75 40 at Ohio State's pro day in 2010.
Sealver Siliga (6-2, 305) was an undrafted free agent out of Utah who spent training camp with the San Francisco 49ers but was among their final cuts. Siliga exited Utah after a junior season in which he was an honorable mention on the all-Mountain West team.
Rose and Siliga would be possibilities for the practice squad to fill the void left by Chastin West, who was signed to Jacksonville's 53-man roster on Monday.
