The NFL attempted to reach out to troubled Titus Young well before his bevy of off-the-field incidents, according to a report by Yahoo! Sports.
"It was someone very, very close to him who was just concerned -- really concerned," Vincent told Yahoo! Sports. "Once we got the call, we sent someone out to meet with him."
Young's problems have been well-documented. The 23-year-old has been arrested three times in just the past month in California, including twice in one day. He remains jailed in Orange County and faces up to 10 years in prison on 11 counts of burglary, attempted burglary and assaulting officers. He also may face prosecution for a DUI charge.
Vincent, according to Yahoo!, said his department "tried multiple" times to work with Young without any success.
"We were told he was not interested in support," Vincent said. "We went to people very close to his center of influence, to reach out to see how we can support him. The response was of someone who is not open arms to being supported."
Vincent's department is geared around assisting current and former players with off-the-field issues. The league has a hotline for players and their families to call 24 hours a day.
"We can reach out, which we have done," Vincent said. "We look to assist and support -- to get him on track. We've reached out. We have been reaching out prior to his last incident. We've been working hard for quite some time in this situation. Everything is available to him."
Vincent, who played in the NFL for 15 years, also told Yahoo! he remains hopeful of being able to help Young.
Young's father recently told two Detroit newspapers that his son suffers from a mental health disorder and desperately needs help.
The Lions drafted Young in 2011 but released him in February after a drop in productivity and disputes with teammates and coaches.
