Veteran tight end Antonio Gates remains a free agent, but he has the support from an established leader for a potential return to his former team.
"I'd always be excited if he walked back in the door," Rivers said, via Jack Wang of the Orange County Register. "It would get my vote."
Gates, who turns 38 in June, would fill an immediate need and could hit the ground running given his past chemistry with Rivers.
While his production declined in 2017 as Henry emerged as the go-to option, Gates remains one of the most prolific tight ends in NFL history.
Gates has 927 catches for 11,508 yards and 114 touchdowns over his career, and has been selected as a three-time first-team All-Pro (2004-06) and named to eight Pro Bowls.
