The Times reports that the team is "bracing for possible penalties." Angels general manager Jerry Dipoto told the Times that Hamilton is in New York for a meeting with league officials, but did not say why.
Hamilton's father-in-law, Michael Chadwick, told Newsday's Steven Marcus that the player has "hit a bump in the road, keep him in your prayers."
Hamilton is currently rehabbing his shoulder in Houston after undergoing surgery earlier this month. The 33-year-old is expected to be out for six to eight weeks and is doubtful for Opening Day.
In 2004, Hamilton was suspended for the entire season by MLB for violating the league's drug policy. He did not make his major league debut until 2007, with the Cincinnati Reds, then spent five years with the Texas Rangers. He was named the American League MVP in 2010.
Hamilton has three years remaining on the five-year, $125 million contract he signed with the Angels in December 2012.
