The Texans signed cornerback Derrick Jones, cutting undrafted rookie wide receiver Stephen Louis.
Jones is a former sixth-round draft pick from the New York Jets.
He was last with the Green Bay Packers.
Jones is a bigger corner at 6-2, 188 pounds.
At Mississippi, Jones moved to corner from wide receiver. He was suspended for three games as a senior for violating team rules.
Cut by the Jets this month and claimed by the Packers, he was waived by Green Bay with a failed physical designation.
