Bournemouth midfielder Andrew Surman is set to miss the rest of the season with medial knee ligament damage, according to boss Eddie Howe.
The 30-year-old, who is a key figure for the Cherries, was forced off shortly after half-time in the goalless draw with Southampton on Saturday.
Surman collided with Saints goalkeeper Fraser Forster in the first half and eventually had to be replaced by his manager.
“They can be quite nasty injuries, depending on the area and how big the damage to the ligament is,” Howe said. “Whether it’s a season-ending injury, we’re not quite sure at this moment.
“I think every player’s different and they bring their own influences to the team. They all have their different strengths.
“Andrew for me is a very, very good controlling midfielder for us in terms of possession, does a lot of work that’s unseen, is good defensively for us as well.”
