Cops Searching For Kansas City Chiefs Rashee Rice

7:50 AM PT -- Dallas PD tells TMZ ... "Police were called to a multi-vehicle accident in the 6600 block of northbound North Central Expressway. The preliminary investigation determined two drivers, one in a Corvette, the other in a Lamborghini, were speeding in the far-left lane."

Cops add, "The drivers lost control and the Lamborghini traveled onto the shoulder and hit the center median wall, causing a chain reaction collision involving four other vehicles." A total of 6 vehicles were involved in the crash, too.

Dallas PD goes on to say "The occupants of the Lamborghini and the Corvette all ran from the scene without stopping to determine if anyone needed medical help or providing their information. Two of the involved drivers were treated at the scene by Dallas Fire Rescue for minor injuries and two occupants of another vehicle were taken to a local hospital with minor injuries. The investigation and identification of the suspects are both ongoing."

Cops are on the hunt for Kansas City Chiefs wide receiver Rashee Rice ... and it's all over a very bad car accident.

A car registered to Rice was involved in the crash, which occurred just after 6 PM Saturday ... this according to the Dallas Morning News.

It's unclear the extent of any injuries ... ditto why cops are looking for Rice. It seems police believe Rice, whose team won the Super Bowl this year, may have left the scene of the accident without leaving identifying information, although the details are unclear. It's also unknown who caused the crash.

There are few details available so far, expect the accident is being described as "major." There was an accident reported in the same area and around the same time -- with the aftermath being captured on camera.

We checked with the jail and it seems so far, cops have not located Rice.

TMZ reached out to both Rice and law enforcement ... so far, no word back.
