Injury-hit Maddy played just two Championship games in 2009
Darren Maddy may have to undergo an operation after sustaining a "nasty" facial injury on Warwickshire's pre-season trip to Bloemfontein.
The former Bears captain suffered the injury while batting in a net session.
It is anticipated that he will require an operation to repair the damage - and he will see a consultant on Thursday.
"It is always nasty to see a player suffer a facial blow but I am confident that he will be back playing as soon as he can," said Bears coach Ashley Giles.
"It is a blow for Madds after missing last summer with his knee.
"But, after consultation with the medical staff out here, with his determination, we are positive that he will make a quick and speedy recovery."
Maddy played just two County Championship matches and a Friends Provident Trophy game in 2009 after injuring his knee last April.
