Knox (foot) will be a limited participant at practice Wednesday, Chris Brown of the Bills' official site reports.
Knox approached the Bills' Week 3 contest against the Dolphins listed as questionable with the same injury, but the tight end suited up and logged 65 of the Bills' 92 snaps on offense while catching all four of his targets for 25 yards. With no reported setbacks coming out of that contest other than an issue with the heat, Knox may just be limited Wednesday for maintenance purposes.
