The 49ers just announced on twitter that they signed seven players to their practice squad, and running back Xavier Omon is one of them.

Omon had a strong exhibition season, rushing 30 times for 121 yards and a touchdown.

The sixth round pick from USC, Ronald Johnson, did not have a strong exhibition season, and the 49ers did not sign him to their practice squad either.

The eighth and final spot will probably go to Keaton Kristick. The Niners waived him today to make room for Scott Tolzien, but Kristick is still practice squad eligible.
