Aston Villa central defender Curtis Davies is hoping to avoid surgery on his troublesome right shoulder which flared up again during the Peace Cup in Spain.
Davies experienced problems with the shoulder when a West Brom player and again last season and the current setback came against Porto on Friday.
But Villa boss Martin O'Neill said: "It is concerning that the shoulder seems a little weak. But at this stage we are not considering an operation to strengthen the shoulder."
O'Neill will step up his attempts to strengthen his squad during the coming few days.
Blackburn left-back Stephen Warnock looks poised to move to Villa Park once Sam Allardyce can find a replacement.
But O'Neill will need to make a quick decision on whether to pursue his interest in Sporting Lisbon midfielder Miguel Veloso.
O'Neill has had Veloso on his radar for the past couple of months but Sporting want Villa to conclude a deal for the £12million-rated player otherwise they will look elsewhere to off-load him.
O'Neill's first choice is believed to be Real Madrid play-maker Wesley Sneijder but it is thought his demanding personal terms are a major stumbling block.
The former Celtic boss is still interested in Portsmouth defender Sylvain Distin but the reluctance of the South Coast club to reduce their £4.5million fee could scupper the deal.
O'Neill may instead offer a short-term deal to ex-Pompey defender Sol Campbell who is now a free agent.
