49ers.com writer Chrissy Mauck checks in with some updates from Monday's practice.
The players are practicing in pads Monday morning and newly signed Takeo Spikes is among them. Spikes is wearing #51 while Dontarrious Thomas is wearing #56. I doubt that these numbers are yet league approved, but for practice purposes anyway, that's what they are wearing this morning.
Check back later today for more updates.
