The 49ers have recently discussed signing either Walker (ankle) or Jordan Reed during the offseason to bolster their tight-end depth, Matt Barrows of The Athletic reports. This is the first notable report of interest in Walker since he was cut by Tennessee in March after missing the final nine games of last season with an ankle injury that required surgery in December. The ankle was the same one he fractured and dislocated in Week 1 of 2018, an injury that ended his 11-year streak playing 15 or more games. The tight end will turn 36 in August and may need to battle for a roster spot if or when he signs with a team. The 49ers are looking for a veteran to join George Kittle and Ross Dwelley in their tight end room.
