Gary Naysmith injury concern for Aberdeen boss Craig Brown
Gary Naysmith is likely to miss Aberdeen's remaining fixture before the international break after straining his hamstring during the draw with Hearts.
Boss Craig Brown fears he may lose the left-back "for a game or two".
"It's a bad one, we're really worried about Gary," Brown told BBC Scotland after the at Pittodrie.
"He joined with us in Germany, halfway through our tour over there and he hadn't the same pre-season as the others before we went to Germany."
Brown praised his players following their performance against Hearts but bemoaned the lack of a breakthrough.
"I've said to the players we're proud of their performance," added Brown. "Obviously, we're disappointed that we didn't get the elusive goal.
"But we couldn't fault the players for the effort that they put in and the structures that they maintained throughout the match.
"The tempo of the game was good, everything in the garden was rosy except the elusive goal.
"It was similar against Ross County a couple of weeks ago when it was 0-0, we missed glaring chances then. We created a number of chances [against Hearts] but unfortunately we just couldn't convert them.
"At the back we were excellent. Jamie Langfield had nothing to do and Russell Anderson came in at right-back and was absolutely outstanding."
