Logos on the floors

[Nevadaref]

How many people have observed players slip on the logo stickers that are placed over the center circle and sometimes on the endlines of the courts for tournaments?
Nevada lost their best perimeter defender to a hamstring injury sustained from this in the first game of the conference tournament. He did not play in their loss in the next game.
Nevada's coach and the WAC conference commissioner disagreed over the safety of these decals.

So what is the opinoin of people on here?
Are these a hazard or are they safe?
Should the NCAA people examine this more closely?

From the Reno Gazette Journal on March 9:

"The letdown only came when starting guard Kyle Shiloh suffered a hamstring injury in the final six minutes of the Wolf Pack's 88-56 win over Idaho in a quarterfinal game of the Western Athletic Conference tournament on Thursday afternoon.
Nevada advanced to a semifinal game against Utah State at 5 p.m. today and might have to play the game without Shiloh, a three-year starter, after he slipped on the WAC logo at mid-court.
"He's probably done for the week," said Nevada coach Mark Fox, who was critical of the large logos that are common in postseason Division I basketball. "We do have a deep team. We have a very deep team, but he's a terrific player.""
