Giancarlo Stanton is headed back to the Yankees' injured list.
Eight days after he returned from a 2 1/2-month absence with various injuries, Stanton will be placed on the IL with a strained right PCL, manager Aaron Boone said after Wednesday's 8-7 win over the Blue Jays.
The 29-year-old Stanton left Tuesday's game before the fourth inning after injuring his knee on the basepaths. He told Boone he wasn't sure if he injured it sliding into second base or diving into third base in the first inning.
Boone was optimistic Stanton, who is hitting .290 with one home run and seven RBIs in nine games this season, would avoid another trip to the IL before Wednesday, telling reporters, "Tests were good -- came in today and there was no swelling in there."
It is unclear how much time Stanton will miss. He will not be on New York's road trip to London, where the Yankees will face the Red Sox for two games.
Clint Frazier will not replace Stanton on the active roster for the road trip. Instead, the Yankees will send Mike Tauchman, Thairo Estrada and Kyle Higashioka to London, according to Newsday's Anthony Rieber.
Stanton was placed on the IL on April 1 with a biceps strain and remained on the IL until June 18 because of a shoulder impingement and a left calf strain.
