Bailey (ankle) reached an injury settlement with the Chargers on Friday, Michael Gehlken of the San Diego Union-Tribune reports.
Bailey signed with the Chargers in early-August, but didn't see a minute of preseason action. The agreement removes him from the team's injured reserve list, leaving him free to sign with another team.
Smelter (hamstring) was added to the 49ers' practice squad, Matt Maiocco of CSN Bay Area reports.
Smelter was cut by the 49ers prior to the season after suffering a hamstring injury during training camp. Prior to the injury, the 2015 fourth-round pick had light breakout potential due to his size and athleticism. It is unclear if and when the 49ers will give Smelter a chance on the 53-man roster, or even if his hamstring injury has fully healed. While he is definitely not a player worth picking up right now, there is still potential for a late-season appearance where the team tries to get a better look at their former top receiving prospect on a team devoid of reliable options at that position.
