McClendon said Cano first felt the injury over the weekend while making a play at second base. He played Tuesday against the Arizona Diamondbacks, but did not play on Wednesday. Instead, he was scheduled to undergo an MRI.
Cano is expected to travel with his teammates to Minnesota after the series finale on Wednesday. The Mariners open a four-game series against the Twins on Thursday.
Cano was replaced by Brad Miller at second base on Wednesday afternoon against Arizona.
Despite hitting just .237 over the first 61 games this season, Cano has hit .306 with nine home runs and 23 RBIs in his last 37 games.
Entering Wednesday, the Mariners are 10 games behind the American League West-leading Los Angeles Angels and Houston Astros.
