Already missing Tiger Woods, the AT&T National will now have to do without U.S. Open champion Justin Rose.
Rose withdrew from the tournament Monday because of fatigue. He says in a statement he is disappointed to pull out of a tournament he won in 2010, but the last three weeks have been mentally and physically demanding.
Rose won his first major two weeks ago at Merion and then tied for 13th last week at Hartford. He won the 2010 AT&T National when it was held at Aronimink.
Woods withdrew last week because of an elbow injury. He won't play again until the British Open.
That leaves Masters champion Adam Scott as the featured player this week at Congressional.
