A Dallas police officer was critically injured in a crash with a wrong-way driver in southern Dallas early Wednesday morning, police officials said. The officer was reportedly driving to work.

Police said the wrong-way driver hit the front left side of the officer's SUV, forcing it to go into the right lane and get hit by a tractor-trailer. The SUV rolled several times before stopping on the right shoulder of Spur 408, WFAA reports.

Police Chief Eddie Garcia tweeted Wednesday morning that the officer was "struck head on by a wrong way driver in a major collision" and that the officer was "fighting in critical condition."

The wrong-way driver was also hospitalized in critical condition.
