receiver has been "made available" by the team ahead of the Nov. 3 trade deadline, according to Albert Breer of Sports Illustrated.
Pettis has been inactive the last two games and had just one target with zero catches in four games this season. His only touches have come with a pair of punt returns.
The 2018 second-round pick had a big rookie year with the 49ers, totaling 467 receiving yards on 27 catches and five touchdowns. His 17.3 yards per reception would have been fourth in the NFL if he had enough chances to qualify.
