The return to play of Robby Fabbri was put on hold Sunday with the team announcing that the forward, coming off a knee ligament injury in February, would be sidelined for the rest of the preseason. The team said Fabbri re-injured his surgically repaired left knee and would be re-evaluated in 10 days. The team said it would have no comment on the injury until then. Fabbri had been projected to play in the Blues’ first preseason game but was a late scratch, and his first appearance was pushed back to the Washington game Friday. He played 19 minutes, 8 seconds in that game, second-most among forwards, and reported no ill effects after his first game. He had an ice bag on his rebuilt left knee when he spoke to reporters Friday in Washington, but that’s hardly unusual for a hockey player, and he said he hoped to get in four preseason games. On Saturday, coach Mike Yeo said there were no aftereffects from the game and that he was expecting Fabbri to be in the lineup for the game Sunday against the Penguins, but he was not on the travel roster the team released late Saturday night.
