Marcos Rojo's absence from Manchester United's first team continues to be riddled in uncertainty as the club continue to delay confirming the Argentina international's injury prognosis after the player suffered a dislocated shoulder in the match against Manchester City.

Rojo required oxygen and was later taken to hospital following a collision with City's Martin Demichelis during his side's 1-0 defeat at the Etihad Stadium. The 24-year-old defender was discharged from hospital on Sunday 2 November but United are still to confirm the extent of the damage.

Rojo's father says the injury will only see the defender miss "two or three" games, which see him return after the international break in time to face Arsenal in the Premier League. However, various media reports suggest the player's absence could range from between six weeks and six months.

Speaking to Argentine TV station, Rojo senior said: "It is not too severe. He will miss two or three games." Rojo himself wrote on Twitter upon leaving hospital: "Thanks to all for the messages. Thanks to God it as just a bad moment."

Though Rojo's absence from the United team is yet to be confirmed, manager Louis van Gaal says he will definitely miss the visit of Crystal Palace leaving the club will a defensive injury crisis prior to the international break.

Phil Jones, Rafael and Jonny Evans' injury problems have been compounded by that of Rojo and Chris Smalling through suspension. Though Van Gaal hasn't hesitated in supplementing the United team with youth players including Tyler Blackett and Paddy McNair, the returning Michael Carrick has pledged to fill the void in defence as he did for much of the loss to City on Sunday.

"If I need to play there then fine, I have not had a lot of football recently so I will play anywhere," said Carrick after making his first United appearance of the season against City after picking an ankle injury during the summer.

"It's not somewhere I have played an awful lot of games. I have had spells of playing there over the years, playing two or three or four games in a season. But I don't mind. I will play anywhere."
