Kroft (knee) participated in team drills at the open portion of Monday's practice, Jim Owczarski of the Cincinnati Enquirer reports.
Kroft previously hadn't taken part in team drills since Aug. 2, when he suffered a knee sprain that was expected to keep him out for 4-to-6 weeks. Given that he missed all of the preseason and most of training camp, Kroft should still be considered questionable for Week 1 against the Jets. Kroft will likely have a key role if he's able to play, as Tyler Eifert (ankle) still figures to miss at least the first week or two of the regular season. If neither Kroft nor Eifert is available Sunday, the Bengals will likely start C.J. Uzomah, with Jake Fisher (ankle) and H-back Ryan Hewitt potentially also stepping into significant roles. Above all else, Cincinnati will likely rely on its running game and wide receivers until Eifert returns, with A.J. Green (knee) in prime position to gobble up red-zone targets.
