BOSTON -- A state police trooper was seriously injured Monday morning while responding to a car crash on Route 290 westbound, near the Plantation Street Exit 22 in Worcester.

The trooper, Edward Bruso , who is assigned to the Holden barracks, was taken to the University of Massachusetts Medical Center after the 7:50 a.m. crash and was released later in the day.

No other vehicles were involved in the accident.

State police also responded to a number of other motor vehicle crashes in central Massachusetts Monday morning, they said, reporting that there was a total of eight crashes in Worcester, Boylston, Shrewsbury and Northboro, Sturbridge, Webster and Oxford.

Some of those crashes involved injuries to drivers. The potential causes of the crashes, including road conditions, remained under investigation.

The roadways most affected were Routes 190, 290, 2 and 495.

Two other Massachusetts state troopers were involved in crashes Sunday night.

At 8:01 p.m. Trooper Patrick McGowan was treated and released at Norwood Hospital after being involved in a crash with a 2004 Acura on Route 1 southbound in Wrentham. A passenger in the Acura was taken to Sturdy Memorial Hospital with injuries.

At 8:20 p.m., Trooper John Duggan was also injured on Route 495 southbound in Raynham after a 2001 Pathfinder going in the opposite direction crossed the median strip and hit the cruiser head-on, state police said.

The trooper had to be extricated from his cruiser and was taken to Morton Hospital with minor injuries. The woman who was driving the Pathfinder was also taken to Morton Hospital.

Both of the Sunday night cruiser crashes remain under investigation.
