Darnell Dockett's rib injury isn't serious and won't keep him out of the regular season opener.
On Monday, San Francisco 49ers defensive lineman Darnell Dockett posted about having a cracked rib on Instagram, and there were reports that the injury was relatively minor. On Tuesday, head coach Jim Tomsula discussed a number of 49ers-related topics on KNBR, and confirmed that Dockett's injury is, in fact, minor.
In fact, Dockett doesn't have a cracked rib at all, but Tomsula did not he has some "cartilage thing," according to Matt Maiocco of CSN Bay Area.
