McConkey (foot) is expected to be at practice Wednesday, Kris Rhim of ESPN.com reports.
The level of McConkey's participation remains to be seen but it appears he'll get some work in Wednesday, according to coach Jim Harbaugh. McConkey has battled through a couple of injuries this season, the most recent being a foot issue that flared up in the third quarter of the Chargers' loss to the Seahawks. The Chargers have a critical game Sunday at home against the Broncos.
