Williams was listed as a full participant on Wednesday's estimated practice report.
Williams' six-game suspension to begin the season due to a violation of the NFL's gambling policy was reduced to four games last Friday after the league and NFL Players Association agreed to an amended policy. The Lions have a roster exemption for Williams until next Monday, but considering the team's top two wide receivers are tending to injuries, Williams could have a decent role off the bat Sunday against the Panthers, despite head coach Dan Campbell's assertion Monday that the second-year wideout won't be asked to handle a full-time role in his 2023 debut, per Dave Birkett of the Detroit Free Press. Williams' situation for Sunday's contest versus the Panthers may change if one or both of Amon-Ra St. Brown (abdomen, no practice Wednesday) and Josh Reynolds (groin, limited practice) are sidelined this weekend.
