Hasselbeck posted on his Twitter site Tuesday he had the "worst bye week ever. 6 year old daughter got hit by a dirt bike."
The 34-year-old father of three said he spent his weekend at the hospital.
He thanked the dentist who repaired Mallory's mouth and the staff at Central Washington Hospital in Wenatchee. He also thanked the staff who treated Mallory at Seattle Children's Hospital upon the family's return home.
He said she will miss her basketball season but will recover.
