49ers signed RB Xavier Omon, C Chase Beeler, OT Derek Hall, WR Joe Hastings, CB Cory Nelms, TE Konrad Reuland, and OLB Monte Simmons to their practice squad. Journeyman Omon opened eyes with a strong exhibition season, rushing for 121 yards on 30 carries. The final spot is expected to go to LB Keaton Kristick, who was waived Sunday. It's interesting to note that a quicker Hastings was kept over sixth-rounder Ronald Johnson, who struggled in preseason action.
