I don't have any information in the wiki about a Trent Taylor retirement. The wiki doesn't contain a page for Trent Taylor (the former 49ers WR/punt returner), and there's no mention of his retirement anywhere in the 49ers' team page or player pages.
That said, if this were in reference to the 49ers' depth chart, here's what I can tell you from the 49ers page:
49ers WR room for 2026: The team reshaped the receiver corps significantly — they added Mike Evans and Christian Kirk, and drafted De'Zhaun Stribling in the second round, replacing Jauan Jennings and Skyy Moore (from the San Francisco 49ers page). With Brandon Aiyuk's status in limbo (essentially untradeable and hasn't filed for reinstatement), the current projected WR pecking order looks like:
- WR1/outside: Mike Evans
- WR2/slot: Christian Kirk
- Young depth/deep threat: De'Zhaun Stribling, Ricky Pearsall
As for the return game, the wiki doesn't specify who'd step in for punt returns. Christian Kirk has some return experience, but there's no confirmed replacement mentioned in the 49ers' coverage.
Could you be thinking of Trent Williams the left tackle (who's playing in 2026 on a new extension but said 2027 is probably his last year)? Or is there a specific report about Trent Taylor retiring you saw elsewhere?
