The Rocky Mountain News reports: Allen Iverson was playing with plenty else on his mind. He had missed practice Monday and Wednesday (the Nuggets were off Tuesday) because his 4-year-old son, Isaiah, had fallen off a stool early Monday morning and suffered what Iverson called a “big gash under his mouth” that needed plastic surgery. “He had hands in his shirt, and it was a high stool,” said Iverson, who said there was lots of blood and his son must go back to the doctor every other day in the next week. “When he fell, he couldn’t brace it. . . . (It was tough because) my wife had to go through what she went through and my kids and (Isaiah) having to go through it. The toughest part was when they sedated him. . . . I was just mentally out of it.”
