Austin Carr tore it up for the Patriots this preseason, but it wasn't enough to garner a spot on the defending Super Bowl champs' 53-man roster, per Jeff Howe of the Boston Herald.
Carr could make the team's practice squad, meaning another team could sign him to its active roster.
Coming in as an undrafted free-agent, the odds for the team's final roster weren't great, especially given how many good slot receivers the Pats already had. Julian Edelman's season-ending knee injury improved the numbers game for Carr, and might be the reason Carr made the practice squad.
