DONS boss Mark McGhee blamed Alloa's artificial surface for an injury scare affecting his promising midfielder Fraser Fyvie.
Fyvie twisted a knee on the plastic pitch at Recreation Park a minute before half-time in Aberdeen's 3-0 Co-operative Cup victory on Tuesday.
McGhee was optimistic there will be no serious damage to his player, but questioned whether turf without the give of grass should be used for more than training games.
He said: "Fraser got a sore one. It might not be as bad as it looked, but I definitely think it's the pitch.
"A lot of these pitches have been built around the country for teams to train on, but I think at this level the competitiveness and the pace that we're trying to play at it does make it a little bit more difficult.
"People's feet are sticking and players are getting injuries. We'll see how Fraser is in the morning, he'll have a scan, but he seemed to be badly hurt with the noise he made. Fingers crossed it's not ligament damage.
"I thought up until that point Fyvie was fabulous and I was gutted for him. He was brilliant tonight, really making it happen."
