London - Bournemouth forward Max Gradel could be out for six months after tearing a cruciate ligament in his knee during Saturday's 1-1 draw with Leicester City, according to British media reports.
The Ivory Coast international, who was sidelined with a similar injury in 2013, was signed by the Premier League club for a reported £7 million from Saint Etienne in August.
The 27-year-old returned to the Cherries seven years after leaving the club, where he spent two separate loan spells in the 2007-08 season.
Bournemouth have already moved to strengthen their squad, signing Crystal Palace striker Glenn Murray on a three-year deal on transfer deadline day.
