BOSTON — First it was pass routes. Now it is hair roots.

Retired New England Patriots wide receiver Wes Welker is still generating a buzz in the region, which was reflected Wednesday as he was part of a full-day promotional blitz with with Massachusetts-based Leonard Hair Transplant Associates. A fan favorite during his playing days in New England from 2007-2012, Welker discussed a variety of topics in various media interviews, including his concussion history and potential long-term health concerns, as well as topics such as his hair.

It was his thinning hair, and a growing bald spot, that initially led Welker to take action.

He said it was one of the best decisions he has made.

Welker, 36, was joined Wednesday by fellow hair-transplant advocates Rob Ninkovich (Patriots defensive end), former Patriots offensive tackle Sebastian Vollmer, former NBA player Brian Scalabrine, and former NFL player Chris Gronkowski, the brother of Patriots tight end Rob Gronkowski.
