ESPN first reported the trade.
Since being drafted No. 8 overall in 2014, Gilbert has struggled, starting just three games in two seasons. Gilbert often looked lost in coverage and was picked on when on the field.
Browns coach Hue Jackson talked up Gilbert's maturity growth this summer. The corner displayed a modicum of improvement this preseason but still looked lost at times. The 24-year-old suffered a concussion in the team's third preseason game.
It's rare for a teams to make inner-division trades, but it speaks to what the Browns thought of Gilbert's progress.
For Cleveland it's another reminder that executive vice president Sashi Brown and the new brass is in full-on rebuild mode with no concerns about jettisoning the previous regime's picks.
