The 49ers made four moves official, signing two players, placing one on injured reserve, and moving one to the suspended list.
The San Francisco 49ers announced four transactions Tuesday afternoon. The team announced the signing of RB Pierre Thomas to the 53-man roster and CB Chris Davis to the practice squad. They have officially moved Reggie Bush to injured reserve, and Kaleb Ramsey has been suspended four games for violating the NFL's policy on performance enhancing substances.
There is no word yet on what Ramsey tested positive for, but it was enough to pop positive, and his future with the team seems a bit in doubt.
