While players getting second opinions are common and often provide clarity for everyone involved, it does usually mean that the injury is more serious than previously thought.
The Blue Jays are very familiar with Dr. Meister as well. Several prospects visited him last year and nearly all of them required surgery to repair the UCL. While Swanson's elbow would be more similar to in the injury that befell Jordan Romano - who managed to avoid surgery - a visit to the doctor likely indicates something significant.
Swanson started last year on the IL as well with forearm inflammation and he struggled to regain upon returning, ultimately being sent down to Triple-A. He recovered nicely though and had a strong second half.
While the extent of Swanson's injury won't be known until after his visit with Dr. Meister, it is concerning enough for the Blue Jays that they went out and signed Dillon Tate to a minor league contract, an insurance policy against anything serious.
Swanson's injury now opens up a spot in the bullpen. In addition to Tate, other pitchers vying for the job include Kevin Gowdy, Mason Fluharty, Tommy Nance, Zach Pop, and Josh Walker.
For now, Swanson and the Blue Jays are in a wait-and-see position.
