The San Francisco 49ers secondary appears like it will be at or near 100 percent on Sunday when they face the Seattle Seahawks. Tramaine Brock and Keith Reaser have been full participants in practice, and Kenneth Acker has been cleared through the concussion protocol, according to head coach Jim Tomsula. Acker was listed as limited on Wednesday and Thursday, but Tomsula said he is full go for Friday.
All three cornerbacks missed the Week 9 win over the Falcons, opening the door for Dontae Johnson and Marcus Cromartie to get into the starting lineup. If Acker and Brock are good to go on Sunday, one would suspect they will be back in the starting lineup. Johnson and Cromartie both played quite well two weeks ago against the Falcons, and Johnson had played well in the last game before he was benched on defense a month prior.
In case you missed it earlier today, David Neumann posted a bunch of statistics related to the 49ers secondary performance. The group has shown some improvement, as has the defense as a whole under Eric Mangini and his staff. The proven success of guys like Johnson and Cromartie adds some important depth to the unit. I don't expect to see Cromartie sent back to the practice squad at this point, but it will be interesting to see if the 49ers rotate him and/or Johnson into the mix a bit more against Seattle. The Seahawks are more focused on the run, so it would not surprise me if we saw a lot more base than normal, but we'll see what Sunday brings.
