Argentina's rugby union lifted the interim suspension of skipper Pablo Matera and two other players for racist tweets on Thursday, in a shock U-turn just two days after calling the posts "unacceptable".
The surprise move followed reports that Argentina's players had threatened to strike over the suspensions of Matera, Guido Petti and Santiago Socino for their "discriminatory and xenophobic" tweets.
the Argentina Rugby Union (UAR) said in a statement.
None of the three players were named in Argentina's team to play Australia in the final Tri Nations fixture in Sydney on Saturday, where Jeronimo de la Fuente will take the captain's armband.
Matera had earlier said he was "deeply ashamed" of the tweets, posted between 2011-2013 and since deleted, including one where he spoke of "running over blacks" with his car.
The historic tweets resurfaced after criticism that the Pumas did not adequately pay tribute to Argentina football icon Diego Maradona, who died last week, before Saturday's defeat by New Zealand.
In announcing the suspensions on Tuesday, the UAR had said:
