Kolek will get a second opinion on his right forearm Tuesday, Jaylon T. Thompson of The Kansas City Star reports.
Kolek emerged out of his rehab start with Triple-A Omaha on July 18 with a right forearm strain, which prompted the Royals to transfer the right-hander to the 60-day injured list July 22. He's eligible to be activated from the IL in early September, but the Royals will have a better sense of Kolek's recovery timeline once he undergoes more tests.
