Chase has been putting in extra work in the aftermath of Friday's preseason game against Washington, when he dropped three catchable balls, Geoff Hobson of the Bengals' official site reports.
Chase went in and worked with receivers coach Troy Walters on Saturday's off-day, and then turned in a big practice on Monday. With Joe Burrow playing in this weekend's preseason finale versus the Dolphins, Chase should get extra work in that game as well.
