TPC Las Colinas in Trouble for Nelson?

The Byron Nelson Championship is just 6 short weeks away and there have been a lot of changes made to the TPC Four Seasons by DA Weibring. A problem has surfaced - a fungus problem, supposedly - that has put that quality work in jeopardy and the tournament site into question.

More from Bill Nichols:

There's so much speculation from players and caddies about the popular tournament that it's hard to separate fact from fiction. Among the rumors: A fungus is ruining the new grass, and the tournament is moving to the TPC at Craig Ranch.

PGA Tour officials examined the course Monday. They are awaiting results of a soil sample that will probably come Friday. A decision on the redesigned layout is expected early next week at the latest.

One certainty is that D.A. Weibring's remodeling job got a big thumbs-up from the Tour. But with only six weeks to go, durability of new grass is a concern.

Tim Finchem commented on the visit and the implications of the timing of it.

"We're at a point with Las Colinas where we're building staging down there, so we've got to make a call," Tour commissioner Tim Finchem said. "The visit that was done Monday was very positive. There's no question about the quality of the golf course. But we've got to have good grass, and the greens need to come through."

I spoke with DA Weibring last year about the changes they were implementing. He seemed incredibly excited about them and was getting a lot of support from the players that demanded the change.
