CHICAGO &ndash; A 15-day suspension that trainer Mike Stidham began serving Dec. 4 for a medication positive has been stayed by the Illinois Racing Board, and horses racing Thursday at Fair Grounds will run in Stidham&rsquo;s name rather than for Hilary Pridham, Stidham&rsquo;s longtime assistant who had taken over the operation during his suspension.\r\nThe racing board issued the stay as it continues to sort out the particulars of a positive called on Upperline after her win July 3 in the Arlington Oaks. Upperline tested positive for the nonsteroidal anti-inflammatory drug etodolac, which is not permitted at any level on race day in Illinois. Besides the 15-day suspension, Upperline&rsquo;s positive test also triggered her disqualification from the Grade 3 race.\r\nStidham, who declined to provide details concerning the stay, appealed the ruling, and a hearing was to have been held on the matter Dec. 13. That hearing was canceled, however, and Upperline&rsquo;s case has been remanded back to stewards for further consideration. The stewards, now at Hawthorne, could issue a new ruling on the positive test in coming days, officials at the racing board said.
