Teammates are concerned about embattled Miami Dolphins offensive guard Richie Incognito's recent irrational behavior and mental state, according to league sources.

Incognito admitted to Scottsdale police that he inflicted damage on his own Ferrari with a baseball bat in front of his home.

According to a source, Incognito hasn't been difficult to get in contact with for the past few months and has been out of contact with most of his teammates.

Incognito has battled anger management issues in the past and was allegedly the primary tormenter of teamamte Jonathan Martin in the Dolphins' bullying scandal, according to NFL investigator David Wells' report.
