Luke Harper and Aaron Rowan had a match against the Prime Time Players. Wyatt was there but he sat in his chair on the stage, never came down, and when the match was over he had quite a visible limp as he walked backstage. Wyatt did not wrestle in a match nor get involved physical at all.
As noted, Bray Wyatt suffered a calf injury of some kind during his match on Saturday in Providence, Rhode Island as opposed to a knee injury. The injury was to the right leg and while there aren’t many details, the injury is not believed to be a serious one.
