Signed under Roberto Di-Matteo from Colo Colo for £1.4m in the summer of 2009, Jara played a part in Albion's promotion to the Premier League.
He then played a part back in the top flight - netting in a famous 3-2 win away at Arsenal in a season that saw Albion survive relegation.
His tough tackling displays as a central midfielder were what Albion fans will remember him for - while the dynamic Chilean also featured in a number of other positions including right back and centre back.
