Clubs that have 38 players - not including veterans - on their lists are eligible to nominate a rookie to play during the home-and-away season and the finals series if the inclusion satisfies the total player payments requirements.
That leaves Miller free to play against Carlton on March 24 and Lower to face the Brisbane Lions on March 26 after both put in full NAB Cup/Challenge fixtures with their respective clubs.
Miller, 27, was thrown a lifeline by the Tigers in last year's NAB AFL Rookie Draft after being delisted by Melbourne post-season.
Meanwhile, Lower's AFL career was resuscitated by Fremantle after his four-year stint with Port Adelaide ended in late 2009.
Joining the hopeful duo as nominated rookies are Carlton's Ed Curnow, Hawthorn's Riley Milne and Melbourne's Michael Newton.
Earlier on Tuesday, Hawthorn announced former Melbourne big man Paul Johnson would join its rookie list after training with the club's squad across the pre-season.
Johnson, Travis Tuck and Nathan Ahmat-Watkins had been invited to complete summer training with the Hawks in a race to win the final rookie spot on their list.
The Hawks said the decision was "football-based" after they identified a need for an additional tall player, likely to be put in place in case ruckman Max Bailey's knee troubles are not brought under control.
Richmond had invited its former defender Travis Casserly, Victorian Mitch Keddell and South Australian Liam Corrie to train at Punt Road but later decided not to fill its final rookie position for 2011.
The field narrowed to just Keddell and Corrie earlier this month when Casserly was suspended by ASADA for two years for testing positive to the performance-enhancing drug pseudoephedrine after the last season's WAFL grand final.
