Joseph is questionable for Sunday's game versus Indianapolis with a hamstring injury, Scott Petrak of the Elyria Chronicle-Telegram reports.
The 27-year-old has 23 total tackles and one interception through four games, but his status for Week 4 is up in the air. Coach Kevin Stefanski said the team will use the next 50 hours to see how Joseph responds after suffering the injury Thursday, so he may end up being a game-time decision.
