The rib injury suffered by 49ers defensive tackle Darnell Dockett in last weekend’s preseason game vs. the Broncos is not believed to be serious.
Tuesday, 49ers coach Jim Tomsula said Dockett has a cartilage issue, not a cracked rib, and Tomsula said he expects Dockett to be available for the Sept. 14 season opener.
Dockett posted a picture on Snapchat Monday while receiving treatment and called it a cracked rib.
Dockett, 34, did not play last season after suffering a torn ACL in the preseason while he was with the Cardinals. He’s expected to be a rotational player on the remade 49ers defense.
