The Bengals' next session of their first set of voluntary Organized Team Activities is Thursday at Paul Brown Stadium.
The rest of the Bengals' OTA schedule is June 2-4, and June 11-13.
Following the OTA is the mandatory mini-camp June 16-18.
The Bengals are keeping things cloistered this first set of OTAs. Tuesday's session and the June 2 and June 9 sessions are open to the media. Everything else is closed.
Hoping to be a go on the practice field after missing Tuesday's first day or being limited to the rehab field are wide receiver Marvin Jones (hamstring), linebackers Rey Maualuga and Sean Porter (knee), safety George Iloka (unspecified injury) and defensive end Margus Hunt (unspecified).
Bengals head coach Marvin Lewis has challenged Jones this offseason, saying at the NFL Scouting Combine that the receiver needs to prove his worth.
Jones, out all last season with foot and ankle injuries, was thought to be cleared for Tuesday, but he missed the entire day, then was cleared later Tuesday after a hamstring injury forced him to miss pre-OTA physicals.
Those missing the first day who are not expected to be on the practice field include linebacker Vontaze Burfict (knee), offensive tackles Andre Smith (triceps) and Cedric Ogbuehi (knee), and defensive tackle Devon Still.
Burfict and Ogbuehi will remain sidelined indefinitely. Smith is out, but for a briefer time frame. Still is with his daughter, Leah, while she recovers from cancer treatment.
