Jackson received an indefinite suspension on Aug. 31, 2012, for violating the league's substance abuse policy. He had signed a one-year contract with Washington earlier that spring, and that deal was rolled over until the suspension was lifted.
He was on pace to start with Washington in 2012 had he not been suspended. But after missing two consecutive seasons, it's debatable what sort of help, if any, he'll provide.
Jackson started 56 games with Tampa Bay but was suspended twice for violating the league's substance-abuse policy. He received a year-long suspension in September 2010 and returned the following year in October.
He has played in only 10 games since that 2010 suspension and had to deal with a shoulder injury that bothered him during the 2011 season.
