London Irish full-back Tom Homer is set to miss the start of the new season due to a "significant" groin injury.
Homer was in some pain as he attempted a penalty for Irish in a pre-season friendly against London Wasps last weekend.
The Premiership's top points scorer in 2011-2012, Homer is now set to be sidelined for an unknown period of time.
The 23-year-old was due to see a specialist for a second time on Thursday in order to determine the damage and whether surgery would be required.
In Homer's absence, London Irish director of rugby Brian Smith has hinted that the team will turn to former England international winger Topsy Ojo to take the number 15 shirt.
"It's not good, he went down after his first kick," said Smith to the Reading Post.
"He's got a groin injury to his kicking leg. It's come out of the blue because he's had a very good pre-season.
"We'll get a long line of sight about how long Tommy will be out for once he has spoken with the specialist."
"Topsy was outstanding against Nottingham and we'll bring him into the back three while Tom is recovering."
