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.
