Newcastle crashed out of the FA Cup at Stamford Bridge, and it was the way the Blue's players flew through the air looking for free-kicks that infuriated the the ex-England skipper.
Wright-Phillips obviously overreacted to a challenge by Robbie Elliott, in which the Chelsea player was airborne before he got within two feet of the Newcastle defender, and Elliott was given a second yellow card for doing nothing.
Shearer: "It was a blatant dive. There was absolutely no contact and I thought that at the time. I have seen it again on a replay and it was definitely the case."
The Newcastle skipper was booked for arguing with the decision in the last minute of normal time.
Newcastle's caretaker manager Glenn Roeder: "My view is crystal clear. Wright-Phillips took the ball past Robbie Elliott, who immediately turned his body sideways to let him go. He is an experienced defender - but Wright-Phillips knows he has beaten him and he's on the ground. He made no attempt to run past him at all.
"I am disappointed with the young man - and I don't think his dad will be too pleased either. What disappoints me most is the contrast between two incidents in the game. Kieron Dyer was 'scissored' in the corner but he gets up straightaway and he is not looking for a foul or a booking.
"Then we have the sending-off incident. They are at two ends on the spectrum of fair play. I am sure the other manager will have his opinion - but that is mine."
Chelsea boss Jose Mourinho refused to speak after the game. But ex-QPR player Gerry Francis spoke on SKY TV saying: "Alan Shearer should be careful because only Shaun Wright-Phillips knows if he was fouled or not. If Alan Shearer goes into management he should choose his words better."
