With the Colts bringing Ahmad Bradshaw back, there was going to be an odd man out in the backfield, and that turned out to be Donald Brown. Brown has agreed to join the Chargers, according to NFL.com, though terms of the deal are not yet known. 

Brown emerged as the team's primary back in the second half of last season, finishing with a career-best 5.3 yards per carry and six rushing touchdowns. Brown rushed for 537 yards on 102 carries and added 214 yards on 27 catches, the latter of which are both career-highs.

Brown will have to fight for playing time yet again, joining a crowded backfield that already features Ryan Mathews and Danny Woodhead.
