According to Houston police, the FBCSO deputy was on a motorcycle working an extra job doing traffic for a funeral.
Police said an Isuzu Rodeo failed to yield the right-of-way and struck the off-duty officer on Martin Luther King Jr. Blvd. at Bellfort Street.
Officials said the vehicle dragged the deputy across a couple lanes of traffic and hit two other vehicles in the process.
The deputy suffered only minor injuries and was taken to Memorial Hermann Hospital for treatment.
It was unclear if anyone else was injured.
