Celtic were credited with an interest in the right-back earlier this year.
A player recently linked with a move to Celtic has moved to an agency that represents several Bhoys players.
But while Lennon was later named Brendan Rodgers' permanent successor, no such move for O'Donnell materialised - despite Kilmarnock's apparent willingness to sell - as the Ulsterman turned to Hatem Abd Elhamed and Moritz Bauer to fill their problem position.
Bauer, though, is only on loan until the summer, at which point O'Donnell's contract is due to expire.
And the latter player's decision to switch to a different agent, as confirmed by his new representatives StormSportsX on Monday, suggests that he may be seeking a move.
Incidentally, a trio of Celtic stars, Jack Hendry, Jonny Hayes and Calvin Miller are already signed up with StormSportsX - as are several of their Rangers rivals.
Celtic fans - would you want O'Donnell at Parkhead?
