Martin Skrtel handed Slovakia a major boost ahead of the World Cup finals after the Liverpool centre-back completed 90 minutes in an international friendly draw with Cameroon on Saturday evening.
The Reds star turned in a commanding display for the Slovaks as the two teams played out a 1-1 draw in Austria - but he did receive a 64th minute yellow card.
Skrtel saw his domestic season with the Reds ended when he sustained a broken metatarsal against Unirea Urziceni in late February.
Slovakia begin their World Cup campaign against New Zealand on June 15.
Elsewhere, Fernando Torres and Pepe Reina did not figure for Spain in their 3-2 win over Saudi Arabia while Krisztian Nemeth was introduced as a second-half substitute for Hungary in a 3-0 defeat to Germany.
