Two people familiar with the situation say Miami Dolphins tackle Jonathan Martin talked of quitting football earlier in his pro career before leaving the team last week to undergo counseling for emotional issues.

One person said Wednesday that Martin considered giving up the sport because of the way he was being treated by other offensive linemen on the team. The person added that Marin now wants to continue his football career.

Both people spoke to The Associated Press on condition of anonymity because the Dolphins have said little about Martin's departure.

NFL officials are trying to determine whether Dolphins guard Richie Incognito harassed or bullied Martin. Incognito has been suspended indefinitely.

The league is investigating possible misconduct in the Dolphins' workplace.
