ALLEN PARK — Wide receiver Titus Young returned to Detroit Lions practice today (Wednesday) 10 days after being sent home for behavioral issues.

 Coach Jim Schwartz said on Tuesday that once Young is back he’ll have to prove himself to the coaching staff to get back into a role on the team.

 Just because he’s at practice doesn’t mean he will be active on Sunday against the Indianapolis Colts.

 Young will wait to address the media until Friday.

 Also returning to Wednesday’s practice were LG Rob Sims and RT Gosder Cherilus.

 Left tackle Jeff Backus (hamstring) didn’t practice. On Tuesday he said he was improving and has a chance to play Sunday.

 Running back Mikel Leshoure was out. Not sure if it’s an injury or personal day.

 Also out were Louis Delmas (knee), Cliff Avril (back) and Corey Williams (knee).
