Glasnow (elbow) was placed on the 60-day injured list Thursday, Neil Solondz of the Rays Radio Network reports.
The move was an inevitable one, as Glasnow is still recovering from Tommy John surgery in early August. He has a chance to return in 2022, but that won't occur until very late in the season if it happens at all. His 40-man roster spot will be taken by new signing Jason Adam.
