Reading manager Brian McDermott has expressed his disappointment with the officials after his side were beaten 4-2 at Chelsea.
Fernando Torres was clearly offside when his goal made it 3-2 to the hosts as they came from behind to win at Stamford Bridge.
"It's just a shame really," McDermott told BBC Sport. "I'm disappointed for the players. I'm gutted the linesman made a mistake for the third goal.
"I've spoken to him, he said he'll look at it. He's a clear yard offside. The linesman will be disappointed with himself I'm sure."
Next up for Reading is a trip to Sunderland on Saturday.
