The Colts placed McLeod (undisclosed) on the active/PUP list Sunday, Chris Widlic of CBS4Indy reports.
McLeod signed a contract with the Colts at the beginning of April following three seasons with the Eagles. The extent of his injury remains unknown, but he's eligible to return at any point before the initial 53-man roster deadline. When available, he figures to play a key role in Indianapolis' secondary.
