- (soccer) Collectively, the defenders of a team.
2010 December 29, Chris Whyatt, “Chelsea 1 - 0 Bolton”, in BBC:
- Battling Bolton disputed the goal, claiming Drogba was offside, but the Ivorian appeared to have timed his angled run across the visitors back line to perfection to race onto a fine Michael Essien pass and ensure Chelsea moved back into fourth place in the Premier League.
- (field hockey) The line running across the goal to the corners of the playing field.
- (rugby) The seven players who do not play as forwards and whose primary responsibility is defense.
2011, Mathew Brown, Patrick Guthrie, & Greg Growden, Rugby For Dummies, →ISBN, page 58:
- A running fullback radically improves the attacking prowess of any back line, particularly if she is able to read a play, knowing when it's time to hit the line at pace or to join the line to act as an extra attacker.
