In the exclusive clip above, Dr. Downey is brought to the hospital in pretty bad shape, with his liver bleeding into his chest and unable to speak. Can Rhodes and Halstead (Nick Gehlfuss) save his life?
Unfortunately, the odds aren't looking good for Dr. D. "Downey has a final crisis," co-showrunner Diane Frolov told TVGuide.com about the finale, which will "finish [Dr. Downey's] arc." Yikes!
Check out a sneak peek of the season finale, which airs Tuesday, May 17 at 9/8c, above.
