Halton (knee) participated during the 49ers' training camp practice Thursday, Chris Biderman of The Sacramento Bee reports.
Halton suffered a bone bruise to his knee on the first day of training camp, but he's already back in pads and picking up where he left off. Given that San Francisco is already dealing with a number of other injuries on its front seven, Halton could be expected to play a noteworthy depth role on the defensive line right out of the gate.
