Smith (elbow) is considering undergoing Tommy John surgery after going for a second opinion on his pitching arm this week, Henry Schulman of the San Francisco Chronicle reports.

According to Schulman, Smith will meet with his agent Friday before making a final decision on his course of action. An MRI earlier in the week revealed that Smith had a sprained UCL in his left elbow and now it appears that a Tommy John procedure could be imminent. Smith was acquired by the Giants at the trade deadline and was strong down the stretch with a 1.78 FIP and 26 strikeouts over 18.1 innings. If the Giants lose Smith for a significant amount of time, they'd be missing a significant piece of their bullpen puzzle. More information on Smith's course of action should be made available over the weekend.
