The team announced a two-year contract extension for Walker on Friday. The new deal is worth $14.7 million with $8.2 million in guarantees, NFL Media Insider Ian Rapoport reported, via agent Vincent Taylor.
"We are excited to get this deal done with Delanie," general manager Jon Robinson said in a statement released by the team. "He's an integral part of this offense, and he has bought into our philosophy of what Titan football is about. We are looking forward to his continued impact both on the field and in the community in the future."
Coming in at No. 98 on one writer's Top 100 list, Walker finished first in receptions and third in yards among tight ends last season. His 94 catches set a franchise record for the position.
After seven years in Vernon Davis' San Francisco shadow, Walker has emerged as one of the NFL's most productive tight ends in Nashville.
