Norris (back) made a rehab appearance Sunday with High-A Lakeland and will pitch again there later this week, Matthew Mowery of The Oakland Press reports.
Norris threw 39 pitches Sunday without issue, and he will up that number to around 55 his next time out. He'll likely need another rehab outing or two to build up his pitch count, but Norris has a chance to be back with the Tigers before the month ends.
