Norris (groin) was activated from the DL on Friday.
He wasn't effective in Thursday's rehab start for Triple-A Toledo, giving up five runs on five hits and four walks in two innings, but the Tigers had no reason to keep him on the DL with rosters expanding. Look for him to start either Tuesday or Wednesday against the Royals. Norris has a 5.29 ERA, 1.67 WHIP and 79 strikeouts in 85 innings in the big leagues this year.
