Pittsburgh Pirates rookie shortstop Konnor Griffin will miss eight to 10 weeks with a left ring finger injury, the team's senior director of sports medicine Todd Tomczyk told reporters Tuesday, deepening the club's growing injury concerns.

Griffin had rejoined the Pirates just two weeks earlier following a monthlong absence caused by a right elbow strain. The rookie sustained damage to the sagittal band in his finger, which Tomczyk described as thick fibers that support and reinforce the extensor tendon.

Tomczyk said Griffin will wear a splint for six weeks before doctors reassess his recovery timeline.

Boston Red Sox outfielder Roman Anthony has dealt with a separate finger tendon injury since early May, though Tomczyk noted the cases are not directly comparable. Former White Sox shortstop Tim Anderson offers a closer parallel, having suffered a similar sagittal band injury in 2022 that sidelined him for roughly six weeks.

Griffin has hit .276 with a .736 OPS, 10 doubles and five home runs across 59 games since making his major league debut in early April.

Pittsburgh selected Griffin ninth overall in the 2024 MLB Draft. Griffin signed a nine-year, $140 million contract extension with the organization in April.

The setback adds to a lengthy injury list for the Pirates (46-45), who currently sit in fourth place in the National League Central and three games behind a wild-card spot. Outfielder Oneil Cruz and first baseman Spencer Horwitz remain sidelined with fractured fingers and a hamstring strain, respectively.
