Andy Lloyd is helped off the field in the match against Munster

Back rowers Andy Lloyd and Steve Tandy are set to miss the rest of the season after coming off just three minutes into Saturday's home win over Munster.

Lloyd suffered suspected concussion after a clash of heads, while fellow flanker Tandy left the field clutching his left shoulder.

"It doesn't look good for either of them," said Ospreys coach Lyn Jones.

The early double loss had little effect on the Ospreys as they never looked in danger against the Irish visitors.

But the home side struggled to find any real intensity or cohesion, with Jones blaming Munster's "negative tactics" for a poor encounter.

"The gain line was very difficult for us and fair play to Munster, they twisted the scrums and closed the gap at the lineout," Jones added.
