According to The Houston Chronicle, Johnson, who is hosting the "Triple Threat" show this week from Texans training camp with Sean Pendergast and Rich Lord, will leave Houston as well and return to Boston to be near his children, McCredden said in an email.
"While we will miss Ted tremendously, as he has been a great part of SportsRadio 610 over the last six years, we definitely support family first and understand how he came to this decision," McCredden said.
McCredden said the afternoon show will continue with Pendergast and Lord joined by a rotation of former players and analysts as contributors.
Johnson, 45, played linebacker for the Patriots from 1995 through 2004 after graduating from the University of Colorado. He was a member of New England teams that won Super Bowl championships after the 2001, 2003 and 2004 seasons and was selected to the Patriots' all-decade team for the 1990s.
He also was one of the first former players to speak forthrightly about the impact of concussions suffered during his playing career.
Johnson suffered two concussions in a four-day period during August 2002 and said he sustained several more concussions during his 10-year NFL career. He later was diagnosed as having mild cognitive impairment that his neurologist said was characteristic of early Alzheimer's disease.
