Casas suffered the injury while running to first after hitting a slow roller up the first-base line in the second inning of Boston's 6-1 win over the Minnesota Twins on Friday. He fell awkwardly and was carted off the field before he was eventually hospitalized.

A week and a day after Triston Casas suffered a ruptured patellar tendon in his left knee, another Red Sox first baseman has landed on the injured list.

The Boston Red Sox placed utility infielder Romy Gonzalez on the 10-day injured list Saturday with a left quad contusion, which further taxes the team's depth at first base.
