The Yankees announced the move Thursday, one day after Britton appeared to suffer the injury against the Tampa Bay Rays. Manager Aaron Boone said earlier Thursday that Britton was undergoing an MRI.
Britton is the latest high-profile Yankees player to be placed on the 10-day injured list, joining sluggers Giancarlo Stanton (hamstring) and Aaron Judge (calf) and infielder DJ LeMahieu (thumb). Judge is tied for second in the American League with nine home runs, while LeMahieu leads the AL in hitting with a .411 average.
Shortstop Gleyber Torres, meanwhile, left Thursday's game against the Rays because of a tight left hamstring.
He is being evaluated, per the team.
Torres, who is batting .231 with one home run and six RBIs, stumbled while running down the first-base line after hitting a grounder in the bottom of the third inning. He was replaced in the top of the fourth by Thairo Estrada, who played second base while Tyler Wade shifted to shortstop.
The Yankees made three other roster moves before the game against the Rays, promoting right-handers Ben Heller and Miguel Yajure and optioning utility man Miguel Andujar to their alternate site.
Britton has had an outstanding stint filling in as the Yankees' closer this season while Aroldis Chapman was sidelined recovering from COVID-19. The two-time All-Star is 0-2 with a 2.00 ERA and is tied for the American League lead with eight saves,
