US Representative John F. Tierney’s wife, Patrice, was treated and released from a hospital after her car was rear-ended Tuesday morning, the Tierney campaign said.

“She sustained some injuries and was treated at Beverly Hospital before being released around mid-day,” campaign manager Matt Robison said in a statement. “It appears that having her seat belt on prevented her injuries from being far more serious.”

The statement did not provide further details.

“She and Congressman Tierney thank all who expressed their concern during the last few hours and appreciate the continued thoughts and prayers from friends, family and supporters,” the statement said. “We are reviewing the congressman’s schedule for the next couple of days and will adjust it accord­ingly, so that he can care for his wife.”

John Tierney is locked in a tough race with Richard R. Tisei, a former state senator.

Tierney’s reelection prospects have been harmed by the legal problems of his wife and her family.

Patrice Tierney was sentenced to a month in prison followed by five months of house arrest after pleading guilty in October 2010 to charges of aiding and abetting the filing of false tax returns for one of her brothers, a federal fugitive allegedly running an offshore gambling ring. Another brother, also accused of involvement in the ring, is serving a prison sentence.

John Tierney has not been accused of any wrongdoing.
