Keuchel (back) will return from the injured list Saturday and start at Cincinnati, Scott Merkin of MLB.com reports.
The 32-year-old was previously expected to rejoin the rotation Thursday, but the team pushed his return back a few days to line him up for the playoffs. Keuchel has a 6-2 record with a 2.19 ERA, 1.05 WHIP and 32:12 K:BB over 53.1 innings this season.
