The switch-hitting Navarro is batting .276 with four RBIs in eight games. The move is retroactive to April 22.
"It's not even disappointing, it's just part of the business," said Navarro. "The only person that doesn't get hurt is the one that doesn't play. I've been through this before.
"Obviously, I want to keep playing, I want to keep helping the team anyway I can."
Navarro suffered the injury trying to stretch a single into a double in the seventh inning of Tuesday's 13-6 win over Baltimore. He was thrown out by Delmon Young on the play and grabbed the back of his left leg as he arrived at second base before slowly leaving the field.
"Unfortunately, I felt the pop right before I was going to slide in to second base," said Navarro. "In the back of my mind I had the hope that it wouldn't be that bad, but I kind of knew. I've been through this before.
"Just gotta go through my training and get back as soon as possible."
Navarro told reporters that he would travel to Tampa with the Blue Jays as they start a three-game series with the Rays. He lives near Toronto's minor league complex in Dunedin, Fla., and he will stay at home while rehabilitating his leg.
"It's a little convenient both for the team and myself," said Navarro, whose wife gave birth to a son a month ago. "I get to spend a little time with my family. Especially having a newborn."
Thole hit .269 with three RBIs in seven games at Buffalo. A six-year veteran who previously played for the New York Mets, he's considered a specialist at catching former Cy Young award winner R.A. Dickey's knuckleball.
