Rangers striker Kyle Lafferty will miss the start of the season after being troubled by a groin problem.
Ibrox manager Ally McCoist revealed the Northern Ireland international would be leaving the club's German training camp early to see a specialist.
It is unclear how long Lafferty will be out for but Rangers expect him to miss a "number of weeks".
McCoist told the club's official website: "It was a little bit disturbing last night when we learned that Kyle has a problem with his groin.
"The doctors and the physios had a look at him and decided it was a niggle that wasn't going to clear up over here.
"So we have decided to send Kyle home tomorrow and he is down to see a specialist on Tuesday to try to get to the bottom of the problem.
"We will know better when we get back from Germany but it is a little concerning."
The injury is a major blow as Lafferty, 23, finished last season on top form for the second year running, hitting a hat-trick in the title-clinching victory at Kilmarnock.
McCoist has so far drawn a blank in his search to bring in a striker with a bid for Dundee United's David Goodwillie turned down, although David Healy recently signed a new contract.
The Rangers manager said of Lafferty: "It's a big disappointment for him and it's a big disappointment for us because he and Nikica (Jelavic) finished the season so well and we were hopeful they would start the season in fine form. However, that does not look like the case with Kyle having this niggle."
