"He's going to Orlando for the break and he's supposed to play for [Class A] Lakeland as soon as he can," manager Jim Leyland said. "But I don't know how fast that's going to happen."
Infante hit off a tee in the batting cages Saturday and was planning to try running on his ankle Sunday.
"Progress is slow," Infante said. "I feel good, but it's still slow. I have to continue treatment, continue running. I'll have to get ready for the opening day [after the All-Star break] or try to go to Chicago [on July 22]."
Infante sustained the injury on a hard slide by the Blue Jays' Colby Rasmus on July 3. Hernan Perez and Ramon Santiago have split time at second base in Infante's absence.
