Toronto Blue Jays placed six‑time All‑Star Vladimir Guerrero Jr. on the 7‑day IL Saturday after he suffered concussion symptoms in a collision[colon] with New York rookie shortstop George Lombard Jr. during Friday’s 3‑1 win over the Yankees. The collision left Guerrero’s helmet dislodged; he returned to score the tying run but appeared dazed and later reported a headache. Manager John Schneider confirmed Guerrero still felt a headache on Saturday. The move cleared room on the 40‑man roster, prompting the designation of right‑hander Lazaro Estrada for assignment. To fill the vacancy, the Blue Jays selected outfielder Daz Cameron from Triple‑A Buffalo and recalled left‑hander Ricky Tiedemann. Chase Lee was optioned back to Triple‑A, while Charles Mc Adoo entered at first base in the seventh.

Guerrero bats .263 with seven homers and 46 RBIs. Tiedemann posted a 6.43 ERA in seven games, two starts, across three minor‑league levels this season. The Blue Jays’ roster shuffle underscores the team’s response to injury and the need for depth in the face of a competitive schedule.
