Meanwhile, practice squad receiver Ricardo Lockette - perhaps the fastest player on the 49ers' roster - is playing the role of Ravens speedster Torrey Smith in practice. A former track star at Fort Valley State, Lockette ran a 4.37-second 40-yard dash at the 2011 NFL combine, which matched the fastest time by a wide receiver.

Chad Hall, who stands 5-8, is portraying Anquan Boldin, who had a string of big games against the 49ers when he was with the Cardinals earlier in his career. Boldin also had a strong game in the Ravens' 16-6 win over the 49ers last year. He led all receivers with four catches for 63 yards.
