Australia defender Rhys Williams was remaining calm despite finishing Tuesday night's 3-0 friendly win over Canada in a protective boot.
The Middlesbrough captain performed impressively at right-back before being replaced by Oliver Bozanic with just over 20 minutes remaining at Craven Cottage.
The injury forced Williams straight into a moon boot but he suggests it may only be a minor problem ahead of Boro's Championship clash with Barnsley on the weekend.
"We'll see what happens," he said. "Hopefully it's just a bit of bone bruising and nothing too serious. We'll check it out tomorrow."
Of his starring role on the right side of defence, the usually centrally deployed Williams added: "Playing right-back sometimes can be difficult because I don't play there for my club, but I never want to let the team down.
"I don't want to let the boss down, but it is difficult switching. But if we're playing with some holding players like we did tonight with Mile [Jedinak] and Dutchy [James Holland] it obviously helps myself.
"I really enjoyed tonight and having Lucas [Neill] alongside me helps as well."
