NEW YORK (AP) — New York Jets assistant coach Greg Knapp was hit by a car while riding his bicycle in California in a “horrific” crash over the weekend.

Knapp, 58, was struck Saturday in the city of San Ramon, in the San Francisco Bay Area. The longtime NFL assistant was hospitalized and was in critical condition Tuesday, said Lt. Tami Williams of the San Ramon Police.

The accident happened at close to 3 p.m. and the driver involved is cooperating with the investigation, Williams said in a statement. A preliminary investigation showed drugs or alcohol did not appear to be a factor in the crash, she added. The nature of Knapp’s injuries was not immediately known, and Williams said in an email she couldn’t release any other details.

Knapp, who lives in the neighboring city of Danville, was hired by the Jets in January as part of new coach Robert Saleh’s staff, serving as the pass game specialist. Among Knapp’s primary roles is to help develop quarterback Zach Wilson, the No. 2 overall draft pick.

Saleh played football at Northern Michigan University in Marquette from 1997 to 2000, going on to coach at the college and pro ranks before getting the Jets’ top job in January.
