Blackburn midfielder Vince Grella ruled out for season
Vince Grella has only played seven times for Rovers this season
Blackburn midfielder Vince Grella will not play again this season after an operation on an Achilles injury.
The Australian, 31, has played seven times during the 2010-11 campaign, and only twice in the past five months.
Blackburn boss Steve Kean said: "It's been hard for Vinny because he's picked up niggly injuries and this has been quite a big operation on his Achilles."
Grella joined Blackburn in August 2008 and made 19 appearances in his first season, playing 17 times in 2009-10.
He started for Australia in their 2010 World Cup opener, a 4-0 loss to Germany, but injury prevented him from playing in his country's following games, a 1-1 draw with Ghana and a 2-1 victory over Serbia.
Grella played for Canberra and Carlton in Australia before moving in 1998 to Italy, the land of his parents' birth, where he played for Empoli, Parma and Torino.
Blackburn travel to London to face Arsenal in a 1730 BST kick-off on Saturday.
Rovers are currently 13th in the Premier League with 33 points, but sit only one point above Wolverhampton Wanderers in 18th, the final relegation spot.
