Former Detroit Lions wide receiver Titus Young was released from the California Department of Corrections and Rehabilitation last week after serving almost half of his four-year prison sentence for battery with serious injury.

The 29-year-old Young had previously been denied parole in February for the fight he was sentenced to prison for in 2016 — the last crime in a string of offenses that dated back to 2013, when he was released by both the Lions and the St. Louis Rams.

Young previously gave the Los Angeles Times excerpts of a diary he kept while behind bars that attribute the run-ins with law enforcement to bipolar disorder and hearing voices.

“Having bipolar has pretty much torn down my life,” Young wrote in the diary. “It’s been four years of fighting so many different behaviors. When I was first diagnosed, I didn’t want to believe it because I felt my life was too perfect to have bipolar. Football players don’t take medicine. I’m macho. Put me back on the field. But, no, that’s really not what I needed.”

The Lions, who used a second-round draft pick on Young coming out of Boise State, released him in January 2013. The Rams picked him up, but cut ties 10 days later as his behavior grew increasingly erratic.

“It’s kind of hard for me to think wisely in sticky situations where I feel threatened,” Young wrote in the diary. “Taking the medicine allows my mood to be stabilized and helps with hearing voices. Yeah, I have heard voices, as well. The voices came and came from the bipolar. It’s usually when I let my brain relax and focus on others. I can kind of hear them.”

Young’s attorney didn’t respond to a request for comment.

Hopefully he was rehabilitated and can live out the rest of his days as a free man.
